The Heljan 2300 Class 23 D5900 in green livery with small yellow panels is a pre-built model railway locomotive in 1:76 scale. This analogue-controlled locomotive features a Bo-Bo wheel configuration and is designed for use on a two-rail system. Perfect for collectors and transportation enthusiasts, this British Rail themed locomotive offers a realistic and detailed addition to any model railway layout. This one of many from my late uncles collection. I tested it on his model rail way before I dismantled it and it was working. Looks like at both ends one of the two things that stike out is missing see photos
