I've finally finished converting my third and last Lionel diecast coal hopper to two rail.
The wheel sets are modified Lionel trucks with NWSL 36" diameter wheels.
I took these photos outside. I think the natural sunlight makes any model train look a lot more realistic.
Lastly, this paint scheme is from the Lionel commemorative fleet of diecast coal cars. The N&W scheme is my favorite.
