This train is completely made up of Cambrian Kits. The train consists of 3 Seahorse, 1 Borail (Mullet) and 1 Salmon. All are very good kits that make up very easily in reasonable time. This is a more recent project, having been completed in the last two years. I used Railmatch Paints and Fox Transfers.
Cambrian have an excellent range of engineers wagons and I can not recommend them any higher.
I sometimes run this train with two other salmon, each fitted with two hi-abs. These are used to recover rail from the trackside. The Hy-Ab kits were available from Genisis Kits at the time.
