      I guess this is the main reason. I guess it's designed mostly not for human transport, it's for freight. And a crate does not get off the train and attaches itself to a truck all by itself...

          The common American term is "piggybacking" - more officially known as TOFC (trailer on flat car).

          The modern implementation of TOFC started in the mid-1950's - special flats cars were being built in the early 1960's (often owned by Trailer-Train) - the earliest implementation dates back to about 1920, didn't take off then because of opposition from the state highway authorities (trucks were avoiding road use fees).

          For long hauls - it makes more sense just to use the box (i.e. containers) - as it reduces weight and air resistance. The Espee pioneered double-stacks (i.e. stacking two containers on one car) with articulated car-sets to further reduce tare weight and train length (single stack trains were too long for the sidings).

          To answer your question - the onde advantage of this approach over TOFC is that you can have much smaller trains.

        Actually, this *has* already been done for freight. I can't find links at the moment, but Swift has trailers that they tie together with rail "dollys" ... you can recognize these trailers because they've got smaller wheels mounted on them than the standard trailers and they have locking points on the rear deck.

        Unfortunately, BNSF is the only rail line that'll run them right now because there's a significant risk of derailing. There's a lot of side-to-side flex put on any rail car, and most rail cars are stiff enough to take it -- but making a road/rail car stiff enough would end up making the trailer too heavy for the tractor to pull it. The road/rail cars that Swift uses have a tendency to twist while in motion, and things can break or snap and cause a derailment.

        Neat idea, but knowing what I know about those swift trucks, I wouldn't ride in a rail/road passenger vehicle ... no way, no how.

      Currently [networkrail.co.uk] it's approximately 21,000 miles of track, 1,000 signal boxes 9,000 level crossings, and 2,500 stations. There's about 10,000 mainline passenger train movements each day in and out of central London alone.

That at least one of it's employees ride along as a "pilot". In addition, steep fees are assessed the other railroad to use it's tracks.

She asks the dispatcher if they have a diesel, a coal burning engine, a switch engine or anything at all. Nothing. Then she asks if they have a track motor car. Which they do, so the crew can come out on that.

      If you read the site, they note that there have been previous solutions that do exactly what they're trying to do here. The advantage they claim is that their design doesn't attempt to power the rail wheels, and instead uses the main tires to provide power and braking. They say that this results in a significant cost savings.

      There's also what appears to be some clever design work which allows the operator to reduce the amount of weight placed on the tires to increase fuel efficiency while cruising, but then rapidly change the weight distribution so as to press down hard while braking.

      A good rule of thumb for stopping distance is roughly 1 meter per kph in daytime, about 1 1/4 at night; I've heard that at 80kph (which is exactly 50mph for those of us in the States) the distance is about 81 meters (about 245 feet) and at night it's about 95m (about 300 feet).

      Not a chance. You don't know anything about railroads, do you? They already thought of this.

      Every railroad operates on a "block" system. This is an interlock designed so that only one rail vehicle may enter an area of track at a time. At the start of each block is a red / green signal and either a speed limit sign or an automated transponder to tell the operator the maximum speed limit for the block they are about to enter. The area of a signal block is something large enough for a train to come to a complete stop, or if necessary, when a train enters a track the signal for the block it is in and the block before it (to allow for any train following it) become red. The faster trains run in an area the larger the block is (or the more preceding blocks are also interlocked). Once a train enters a block, the signal behind it at the entrance to that block turns red and stays red until they enter a new block or change to a different track. It may also cause the transponder in the block behind it to order approaching trains to reduce speed in case they get to their block before they are clear so that they won't have trouble slowing down if necessary. Only once it is completely clear of a block will the signal for that block turn green again. A train operator who sees a red signal will stop their train and not enter the block until it turns green, same as you will stop at a red light when operating a motor vehicle on a street.

      An automated train will warn the operator that the next block is occupied and if he fails to bring the train to a stop and crosses the red signal anyway, it will trip the emergency brakes and the train slams to a stop. This is why it's said when a rail engineer runs a red signal he "tripped a signal." If the engineer enters a block at a speed faster than the transponder it will either apply braking or give a warning then trip. The rail system is designed to prevent this sort of thing from happening. This system is also in place in the event of rail fissures, there is a small electrical current running along the rail, if any rail comes loose, it breaks the connection and turns the block red so a train can't enter it, or possibly opens an earlier switch so trains can be routed around the block, I'm not exactly sure.

      I do know that rail systems are specifically designed to prevent this sort of thing in the absence of negligence or intentional misconduct. If a train operator ignores signals in some cases they may be able to run red lights (on non-automated trains) but the scenario you describe can't happen except by intentional misconduct or flagrant negligence. Besides that

    The idea of a road vehicle driving on rail part of the time, even the way of doing it (guidance by retractable wheel while power is supplied through the road wheels) is in daily use. Just check track maintenance vehicles.

    I also seen several ideas on regular busses being fitted with guide systems so that could be driven without steering in between concrete guiderails. The advantage? It would require only track not a full road. The "hole" in the middle would make watering a lot lot easier while also leaving the area greener (and stop passenger cars from driving accross buslanes). At the same time the busdriver has less to concentrate on.

    This idea seems more aimed at existing tracks. Plenty of places in the world where the old local railroad never been pulled up after the line was cancelled that could use the "faster" route for rural lines. I personally travelled by bus along a previous railroad route. Or rather the bus detoured a lot to zigzag accross highways while passing villages that if it had been following the railroad it could have served. I know because the railroad is used as a museum and the historical steam train journey is shorter then the bus journey.

    So I do think the idea got some merrit, just not for freight. No big operator of a railroad is going to allow a vehicle like this. The biggest problem on the highspeed networks (where you need the signalling to be able to drive insanely fast in the worst of weather, old dutch commericial had a race driver boasting he could beat the speed limit in thick fog. He was sitting in a train :p ) is the number of vehicles that can be fitted. Better to run a few big trains then try to fit countless tiny busses on your major lines.

    Since old rural lines tend to run from city center to village center a truck would have little point going there.

    So a nice idea to breathe some life back into old rural lines without all the problems of busses (busses often don't really "fit" onto rural roads wich are often not designed for fast local traffic).

    But as I said I seen this kinda thing before. About the closest I seen in practice is de "noord-zuid-as" bus "road" that operates in Amsterdam around the airport. Wich is a normal bus but a bit longer and drives on its own concrete road bypassing other traffic.

    In Arnhem there is a trolley bus that can more easily leave the electric grid it is usually connected to by carrying its own generator. Allowing clean silent transport in the city but even more room to manouver then a normal trolley bus (they got tiny generators making off grid travel slow and noisy).

    One thing I got a problem with however is their boasting about braking distances. Trains brake a lot slower and this is a good thing. People walk in a train, last thing you want is to stop so sudden all the people end up in the first carriage. Busses have a slight advantage that if they have an accident then it tends to be with passenger cars meaning they sorta just keep going. Fast braking with all your passengers loose is not a good thing. There been a few accidents with busses and lorries and the results are people dying at slow speeds. Unless this thing enforces the use of seatbelts they better make sure that emergency stop is not used.

    I mean you take a train sized vehicle off tracks and put it on the road, and there's all sorts of trouble. Most roads are rated to handle a specific weight vehicle. I mean you wouldn't even be able to navigate train sized vehicles on any street except the widest straightest ones.

    While this is an interesting concept, trust me, it will NEVER happen. I am a contractor in the railroad industry (working with all levels of railroading, from engineers/conductors to high-level management) and have a long family history of railroading.

    • Maybe it will not happen in the US, but in the UK where this is being developed, road-rail vehicles like this, but slightly smaller, have been in use for some years for track maintenance etc. They vary in size from medium lorry down to Landrover at present, also JCB diggers etc, so this is not really new, but many of its details seem to be quite innovative. But it has been done long ago, with bus type vehicles for carrying passengers.

They're self-contained, cheap, and the infrastructure for quick switching of them from one mode of transport to another is already there. Freight is already past these little cartoons. Whether there's any need for passenger transport that's dual mode is another question entirely.
  • If used for cargo, it's going to be far less efficient than to just use a locomotive, because of the savings in doing things in quantity.

    If used for passengers...wait, why WOULD you want to use it for passengers? It's a bus, that can go on railroad tracks. If you're going long-distance, you could just go on the highway instead, and go faster! For short distances, why would you not use a normal bus (at a fraction of the cost) or a car?

    I think dual-mode vehicles make sense, but on an individual scale rather than for buses or trains. If you imagine a kind of scaled-up hotwheels track, fill it with smallish electric vehicles, then add centralized computer control, you could get a transportation system that has the best of both worlds: individual trip scheduling like cars, but avoiding the huge waste of time of having to control the car yourself. This could free up time to write public works pipe-dream posts on /. while you commute to work.

    The cars could have smallish batteries that allow for short range driving under human control off of the tracks to/from your final destination (they would recharge from the grid and would run under fully automatic control while on the tracks). In urban settings, you might always be less than 1 mile from the nearest track on-ramp, so range wouldn't be a issue. For long drives in the boondocks, a small trailer or module with a gasoline or diesel engine could be attached to create a hybrid vehicle.

    People would punch in their destination at the start of the trip, and the central control system would schedule the entire trip ahead of time, thus avoiding all traffic jams (barring software bugs). If the system lacks the capacity to instantly add the trip, it could make a reservation and tell the rider to chill out and get something done before starting; this would be much better than sitting in traffic.

    What if you need to haul cargo? You might check out a virtual trailer at the lumber yard that's programmed to follow a few feet behind your vehicle. Unload it, guide it back to the on-ramp, and then it automatically returns to the store. Or, if you move a lot of stuff, you could buy your own trailer(s); you could make a whole train if you want.

    The vast majority of standard truck and train cargo is comprised of packages small enough to fit in these smallish vehicles. Large numbers of them could automatically move most cargo around the country when traffic is otherwise low. This could save a lot of money on labor, but current truckers would not be pleased.

    Of course, the Denver airport baggage handling system fiasco demonstrates just how hard something like this would be to implement. However, I think that it's still worth thinking about ways to improve over our current choices of wasteful overpowered, oversized automobiles and inconvenient slow public transportation (which is also wasteful because of its low average load factor).

    What if you really just like to drive? I think that the freed-up Interstates could be reallocated as amusement parks. Remove all speed limits and rent out Ferraris and Porches for high-speed joy riding.

    There are places that this would be a hit.

    I'm in Georgia and there are a huge number of rail lines in use for moving agricultural products around. Most people don't notice or mention the trains at all anymore (except maybe at a murmur [athensclarkecounty.com]). But there are many lines still around that are in use and many that have only been out of use since the train companies started downsizing in the eighties due to better roads and cheaper truck shipping costs undercut their monopolies.

    Rails stretch to the more remote parts of Georgia which are barely touched by commercial air. Though in replacement and downsizing theres still a large rail infrastructure that goes to Atlanta suburbs and so forth. The problem is that the roads have become the dominant and unasailable mode of transport here. There are many places that air, river, and rail will not get you even if they are less expensive and with less impact on the environment.

    Imagine a shuttle service on these dual mode transports that can take people from Augusta to Marietta (probably for some religious or S&M convention). Rail could get you most of the way there (and at one fifth of the fuel cost of bus traffic) while the final legs would have to be taken on road.

    Athens has a van shuttle service that goes to the Hartsfield airport in Atlanta on a regular basis. Many people take it because it will get them to Atlanta without a car and they can ride the MARTA train system around Atlanta. The dual mode vehicle, variable destinations of certain passengers, and fairly regular schedule would be a purpose for these vehicles.

    Heck, even Atlanta's Metro transit system (MARTA) could strongly benefit from these vehicles. Right now they have a limited fleet of busses and an electric heavy rail system with a very limited set of destinations. While it would take major restructuring and expense, a hybrid rail/bus system would be very beneficial. Being able to offer. It might be a scheduling nightmare, but having recently gone to San Francisco and seen what a well run mass transit system can do I fully believe they need to start over on MARTA anyway.

    Roads are the only growing, funded, maintained transportation system in Georgia. A hybrid vehicle that allowed use of the extensive rail infrastructure in this state could be a major boost for mass transit.
  • This is an interesting and refreshing approach, that could revolutionize the transportation industry.

    Don't use a comma to separate a subordinate clause from a main clause, except in cases of extreme contrast.

    The first clause needs a verb badly. Adding "It's called" to the beginning of the sentence might be a good start.

    I want to see car trains along major long-distance highways. They'd ferry parked cars along heavily trafficked arteries. That would reduce the tremendous waste of commuter traffic on local streets.

    For example, the shortest road across Brooklyn, from Manhattan to Long Island, is about 10 miles on Atlantic Avenue. It runs from a major confluence of 10 subway lines, a commuter rail, the Brooklyn and Manhattan bridges, a dozen bus lines and a water taxi, out to two major highways and JFK international airport. But it's a local street, with cross traffic, stoplights and turns - so it takes about 45 minutes for each of the literally hundreds of thousands of commuters to drive each way, each day. Under it, and a block over, run 4 subway lines and a pair of commuter rail lines.

    I'd like to drive up a ramp, filling up a railcar, and parking, as the railcar drove away from the downtown terminal headed to the airport. And the same coming the other way. Railcars would leave continuously, as they filled, with a parking lot to accumulate extra arriving cars as railcars departures are occasionally delayed. Another lot at the end would accomodate extra cars accumulating when the exit highways are backed up. That start and end capacity would also allow railcars to be staggered on the existing rail lines, allowing existing rail traffic to share the lanes in the loop.

    A cartrain trip would take 15 minutes. Drivers could stay in their parked cars, but would be required to reenter their cars for departure by at latest 5 minutes before arrival. A fare of 2 dollars each way might even get people to carpool more, especially if carpool lanes were available leaving the exits. The drive time would be predictable, allowing less time alloted to the entire trip. The stressful drive across Brooklyn would be removed, benefitting the drivers and the Brooklynites along the way. Local congestion would be relieved as much as the commuters would be accelerated. Accidents, pollution, road and car wear, and fuel consumption would plunge. And an underutilized transit resource would be used properly, rather than laying idle under a 10-mile traffic jam. All aboard!
    • Here is the problem. You think that by passing traffic jams around the city and landing there in the center will solve your problem. NOT. These jams happen because too much cars around, and if you implement such railway you will simply shift traffic jams from roads to railway station, either to the source station or to the destination one. Either you keep railway traffic low enough to keep city's small streets able to cope with traffic and your source station will have a long-long-long queue (not better tha

      We tried this in the UK for many years. It was too expensive to attract many users, simply because, for good structural reasons, the train is many times heavier than the cars it carries, so the energy saving, if any, is not sufficient to cover the fixed costs. I am not sure, but I think it may still be operational on one route (it was a few years ago), if so it will be overnight on a sleeper train, again added cost, so people don't use it much.
