Why this model matters
The M7 Class was a key suburban and branch line locomotive for the London & South Western Railway and later the Southern Railway. Known for reliability and versatility, locomotives like Class 318 were commonly used on short passenger services and shunting duties, making them ideal for compact layouts and authentic pre-grouping or Southern Railway themes.
How to use it
Place the locomotive on clean OO gauge track and operate using a DC controller (or DCC system if fitted/converted). Ensure wheels and track are clean for best performance. No assembly, paint, glue, or modelling tools are required.
This is a ready-to-run OO scale steam locomotive. Paint, glue, and modelling tools are not required. It is not a toy.
