Sweden Tests World's First Electric Road For Trucks (inhabitat.com)

Kristine Lofgren writes: Electric vehicles are cool, but for industrial vehicles it can be a challenge to get very far on just electric power. That's why Sweden is testing out an electric road where e-vehicles can jump on, get juiced while they travel, and get back on the road. The country just opened a two kilometer test stretch in Sandviken on the E16 where electric vehicles can connect to an overhead system that is very similar to light rail. It's another exciting step towards a fossil fuel-free Sweden. Trucks can use the electric power while riding on the special electric road system -- on regular roads they operate as hybrid vehicles. The testing is scheduled to take place until 2018, which should give the country enough time to see how the technology functions in the real world. Sweden's energy and sustainable growth agencies will fund the project in addition to the transport administration.

      Actually I have been wondering for a long time why trains don't do exactly what these trucks are doing. Many (most?) trains now (at least around here in the US) are deisel-electric with a deisel engine running an on-board generator to make electricity for the wheels. If you had retractable electrical things on the top of the engine to connect to overhead wires you could use grid electricity for the steep grades and other fuel demanding portions of the trip (like the first couple miles out of major rail yards where you are still getting up to speed) and then spin up the diesel as you get into the long stretches of mainline where you only need to overcome air and rolling resistance which are both minimal for a train.

      In addition to this you could do regenerative breaking on these same stretches of tracks to feed power back into the grid when slowing down. Many locomotives already use electrical generators in the wheels (basically just using the motors as generators) as this avoids wear on the wheels and brakes by avoiding the older mechanical brakes. However on long down grades they still have to use the mechanical brakes since they have no way to get rid of the excess energy; the electrical generator brakes just heat up an onboard tank of water which can only take so much heating before they have to fall back to the mechanical brakes.

      So basically all of the things you need to do a hybrid system like this are already onboard a modern locomotive, the only thing missing is the wires above the tracks and the thing on top of the locomotive to connect to them. The thing on top would be a very small cost to add, the wires would be a lot more expensive per mile, however you can choose which sections of rail to electrify since you are going for a hybrid approach which lets you only electrify the most beneficial parts of the rail network.

      Overall I think it is a very good idea and I am surprised I have not seen it implemented or at least discussed. Maybe I am missing something but it seems like it would work well. I guess the main issue would be the large power surge to the grid from regenerative braking and the huge temporary draw when getting up to speed but it seems like this would be addressable without too much difficulty.

On top of that most diesel engines in use today are DC output only, and unless you're then dumping more equipment onto the engine to make a conversion from DC to AC it becomes another problem. You'll see those odd cases where they bring in train engines to provide power somewhere right? They'll hook them up to a convertor before hooking them into the grid and those suckers aren't small, some of them are the size of a boxcar and pulling one of those along just to dump energy back in is a waste when it can be used for cargo. And you'll want them on the train don't think otherwise. Otherwise you have potentially hundreds of points of failure where these live lines could suddenly be dumping DC power onto an AC grid or the other way around.

In some places in the Northeast corridor there's just barely enough room to squeeze a double stack freight car beneath, but you'd need another meter of clearance for safety. That pretty much means that existing electric passenger rail systems aren't compatible with double-stack freight.

Big diesel engines are reasonably efficient; freight rail companies can pass their fuel costs on to customers; and the investment required to electrify track is enormous.
