For those looking for realism and using AVO, real world A300L Fuel Cell seats 57+driver. Thanks for this great asset, OP!

I don't suppose you implemented a Fuel Cell bus depot or charging station to go along with the bus? I never got why the game designers decided to make biofuel busses quiter then standard busses since they are still just a deisel engine. Fuel Cell busses, on the otherhand, are electric engines and therefor are quiter then standared busses. as well as being even more environmentally friendly since the exhaust is litterally exclusivly water vapor, while biofuel busses still produce co2+water vapor, same as deisal engines.

Ok, I understand. The thing is one usally uses birdview and then it is hard to spot the different lines, but maybe you find a solution someday (maybe just add a small part) :-)

All my line colors are at the bottom for a more uniform fleet. This is also because the NewFlyer needs serious revamping to change the line color to top.

Very cool bus and in every way superior to the vanillas except for one thing: the line color is only at the lower part of the bus and hard to catch.
How about changing the green roof to the color of the bus line? Helps to distinguish them faster. :-)
