MTH Premier CSX (#4519) SD-35 Diesel Engine w/Proto-Sound® 3.0 (20-21758-1)
This is a great rendition of the CSX Diesel, Grey color scheme with Royal Blue wheels and trim , a must have if you are a diesel engine fan or a CSX fan
It was only once on my layout , then put on display it a short time and then boxed back up for age keepings.
