Currently the engine is parked on a siding in Muhlenberg Township, (Reading PA area).
It can sometimes be seen from the overpass on Tuckerton Road, looking south if there is not other train equipment parked in the way. The overpass is just a bit west of route 61. The 61--Tuckerton intersection is just south of where 61 crosses highway 222.
If you want to see it, I suggest going over the overpass, turning around, an looking to the right (South) as you go over the overpass in the east bound direction. If you want a picture, I suggest you have someone else drive slowly while you operate the camera. There is no place to stop on the overpass without incurring the wrath of other traffic.
The train is parked on the east most siding, a fair amount south of the overpass.
Perhaps RBMN will move it back to their "Outer Station" near 61 & Bellevue in the spring.

I've seen it stuffed and mounted at "Outer Station." Given a choice, I'd much rather see it live and double heading with No. 425!

It is now on display at Highway 61 & Bellevue by the Outer Reading Terminal.
It is attached to a big Green box car (advertisement).
I don't know if Reading BMN ever plans to make it operational.
I believe they are restoring a T-1 (#2101) for future excursions.

As is often the case, there are earlier threads on this locomotive. Some go back just a little bit--like to 1999!
