There's a bit of discrepancy.
I also used them now a lot in many different situations. I get me more often thinking it should be a bit bigger, than to think it's ok as it is.
I think, about one quarter more.
That would change the game a bit, because the optimal size of a train gets smaller. Now I think it is about 3-4 (optimal balance between speed and load) and then more 2-3. The train should be made also more slow with more load than yet, to underline that.
The question is then: is this useful? Well maybe. And because of that "maybe" I would like to have for the first try just a second wagon, which behaves so, that it can be tried by some players.
