Littleton Junction is the SRC's flagship 00 layout.

It has appeared over the years at many exhibitions. It is a large layout and is basically a two track main line running round a continuous circuit. At one end of the frontage of the layout is the station which gives the layout its name, and a branch line runs off into the large fiddle yard from there. The layout has been modernised. Essentially, the date for the layout has been brought forward and represents the life of the line between 1992-2002. Signalling has being brought up to date, and the whole line made ready for modern image working.

Littleton won the title of "Best Layout" at the Warley National Model Railway Exhibition held at the NEC, Birmingham, in December 2006.
