Table of Train Weights
Here are some trains, and their weights. The headline figure is weight per linear meter of length, but also includes other metrics of interest. Not included is any feature of interior design, such as the number of seats or the number and location of doors, as those reflect choices about seated vs. standing capacity and about the relative importance of quick boarding and alighting.
Most trains on the list are low-speed commuter trains, but a few are high-speed. All are EMUs, except for high-speed trains with dedicated power cars and two DMUs that are included for comparison. All are single-deck except the TGV Duplex, which is as light as a single-deck TGV.
All figures are in metric units. Length and width are in meters, weight in tons, and (short-term) power in megawatts. Load is the average weight in tons per axle; it is not the same as the axle load, which is the maximum loaded weight per axle. To the best of my ability, I’ve tried to give dry weights, without passengers, though I believe the N700 Shinkansen number is with passengers.
For English units, 1 metric ton per linear meter equals 0.336 short tons per linear foot.

The table separates Japanese, European, and American trains, the latter two with hardly any overlap. I did not include too many French and British commuter trains, and those are fairly heavy by European standards, but even they are a bit lighter than the M-7, the lightest modern FRA-compliant train (British trains tend toward 2 t/m, French trains toward slightly more). I did include the lightest European trains I know of but not all the Japanese trains, selected mainly for the big Tokyo-area workhorses (E231, E233) and longer-range, higher-speed JR East trains that I thought were comparable to the needs of longer-distance American regional lines.
Eyeballing the non-American trains, I think it’s fair and unambitious to think of a train of the future that weighs 1.8 tons per meter, can achieve 15 kW/t, and is capable of 160 km/h. Multiple vendors beat that, often by a large enough margin to cushion against the slight weight increase coming from a wider loading gauge. The upshot of this is that any regulatory overhaul and regional rail revival in the US has to be coupled with a large train order replacing older, less capable trains over time, which means dropping an order for several thousand EMUs over 20 or so years. No single company can make all of these, but sharing in the order, as was done for the R160, could work.
One could also mention the mr-90.
It would be interesting to see what this means for operating costs from lost speed over time.
There are so many other variables involved – for example, power. The E231, the lightest train on this list, is very weak, since the services it runs on are at urban transit scale and speed, the main emphasis is on cost and maintainability rather than performance.
Just for comparison with a relatively fast, light-weight train that ONCE ran in the US–any idea where a North Shore Line Electroliner would land on that table?
2.05 t/m, which is comparable to the trains of the era or slightly older outside the US. A German EMU from the 1930s weighed 1.89 t/m, though with a much lower top speed.
This thread may be dead, but I had a thought – is it possible that the high weight of silverliner V and M-8’s is due to them being independent units? They need all their traction equipment, and cannot share that across multiple cars; plus, of course, the fact that they don’t have shared boogies.
I wonder how much a three-car articulated FRA compliant emu would weigh.
Well, we could look at weights of single-car trains, or two-car trains that aren’t very long. For example, the trains that run on the Canada Line are 2-car EMUs, without articulated bogies; they weigh 76 metric tons for 41 meters of train length.
That seems pretty heavy (1.85t/m), especially for non-FRA dc equipment.
Another way would be to look at the AC 25kV mr-90, that runs in Montreal. They come in married pairs of power car/trailer car, with those weights:
Power Car: 57,169 kg (2.2tons/m)
Trailer car: 44,465 kg (1.7tons/m)
The Power equipment adds almost 13tons to the car. So if we assume a three car train with shared power equipment, supporting a single voltage/frequency, but more powered axles, it may be possible to do that in less than 2 tons/m. If the bogeys were shared, maybe another 10-20% could be saved.
ic3, a danish DMU, 3 segments, 4 bogeys, 2 of them Jacobs bogeys, 58.80m, 97t, 1.65t/m.
Renfe 594, a derivative version that exists in Spain, 2 segments, 4 bogeys, non of them shared, 47.35m, 97t, 2.03t/m.
It seems that taking a married pair and turning it into a three-segment train with shared bogeys can stretch it out without too much of a weight penalty, thus reducing weight per length.

(sorry about screwing up the links so many times…)
