you need the newest patches with the new vehicles switches to use it as it supposed to be working

Michael Blunck thanx for the help!!
the train will replace a toyland loc, and will be availabe in all the 4 climates
Here in the Netherlands its our modern diesel passenger train which tranport the passengers instead of busses in the regios without electrical railway
so there arent exactly 140 seats in it, but we have a dumb first class which takes to much room, and some others are standing in a sort of 3th? class.
the total of sitting passengers it can transport are 135 but it has 14 extra standing places, so thats why i tooked 140 as total
the info came from this sites:
http://www.nedrail1435.nl/paginas/gegevens.htm (look at "technische gegevens")
http://mercurio.iet.unipi.it/ns/nsr_3400.html

(action 0 trains props) 04 (lifetime) 0D (runcost factor) 0E (runcost base) 17 (cost factor)
