did youmake sureto enablethe train addon?
Oh ok do you have any other add-ons enabled? If so try it with just the trains ones and the default ones and see if it works. They may be conflicting.Also, dont worry about it now, but next time you should post stuff like this in help :)
just lock it and make a new topic, only admins can move topics
If the add-on was installed correctly and has no conflicts, it should be in the list of spawnable vehicles in the vehicle spawner menu.
