Petrol-electric omnibus cannot go over any bridges?

[pwhk]

And MacAdam road.

Year 1911 here.

I have no idea. The weight limit is definitely over the Petrol-electric omnibus (4t), but it just refuses to go over a Iron Girder bridge (weight limit 11t), brick bridge (33t, 55t) and MacAdam road (33t) too, even when it is empty.

Is this a "no route" thing, or is it not strong enough to go up the ramp?

[pwhk]

It says "no route" and refuses to go over it.

Started another map. It seems it works well at lower altitudes.

The above problem happens in well above altitude of 10.

Can you upload a saved game in which this issue can reliably be reproduced?

[pwhk]

Unfortunately I lost that save and when I try to reproduce it, it returns to normal

Hmm - very odd. If you can find a saved game in which this can be reproduced, please let me know.
