Your figures don't add up. Divide the electric car by 4 or 5 and it's still more than the electric Eurostar train, and that's a high speed train too.

- wilg 3y agoYeah but it still beats the other trains, which is very surprising. Also my second link has more info. I’d prefer better sources on all of this though.
- Symbiote 3y agoThe source is probably an older edition of [1]. The source for that is partly [2]. That splits the figures into 35.2g / passenger-km for electric, and 704.4g for diesel. The per-vehicle-km figures have a 1:3 ratio, but the per passenger figures nearer 1:20, so I think the huge disparity is due to electric trains being on much more heavily used lines. With Eurostar being 6g, they must have very high usage, or maybe the older electric trains really are much less efficient than the newest ones.
