Don't see any driveable traction engines on the DLS but you could use one of these: Traction Engine 1 Steam,<kuid:225064:4023269> in the Drivable Superadaptor,<kuid2:78193:950:1> to make it a driveable item.
You edit the adapter's config.txt file to put the kuid number, of the asset you want to make driveable, in place of the present kuid number (kuid:68787:25139). The adapter folder includes a readme.txt file that tells how to use it.
