Steam train

[Dexion]

I'm looking for the stats of a steam-powered train like in cowboy movies for a post-apocalystic scenario. In which book can I find it? I look in HT but nothing.

And I looking for some advices/ideas of customise it for defenses and tactics to take possession of the train without destroy it ?

Of course I thinking to put some trunks or rocks on the rails, but it easy to clean the way with lots of peoples to do the job and some watchers with guns.
I don't need solutions with mutants/zombies or things like this because it's a Mad Max like scenario.
