Welcome to the website of the Croydon Model Railway Society.

We are a group of enthusiastic individuals who meet on a Wednesday afternoon and evening to operate and develop layouts as well as taking the opportunity to discuss all things related to railways and tramways. Please note that the clubroom may be closed between the afternoon and evening sessions.  We are close to bus routes 60, 166, 312, 407 and 466; the nearest stations are Purley Oaks, Sanderstead and South Croydon. The About Us tab provides more information about the where we are, the history of the society and what we do.

Latest Updates to this Site

Here are some headlines about work underway in the clubroom and recent changes to this site.

  • We regularly provide updates on the layouts that we are building. The latest updates were loaded on 18th May; see more under the Layouts tab, then Under Construction Layouts.
  • Work is underway on five layouts : –
    • 7mm (O Gauge) dockland scene – track testing underway
    • 4mm (00 Gauge) shunting layout – new electrics
    • 3mm (TT Gauge) extension to an existing exhibition layout
    • 4mm (00 Gauge) layout design underway – the largest layout in the club
    • 2mm (N Gauge) test layout being used for block control.


Our layouts cover a wide range of scales including:- 2mm, 3mm, 4mm and 7mm. 

Why not come and work with us on the construction of new layouts. It is a great way to learn new skills and develop ideas for your own layout. We are currently working on.


A large n-gauge layout which has won many prizes on the exhibition circuit in previous years.

It is now a permanent fixture in the clubhouse and is extensively used by members to ‘exercise’ their collection of n-gauge rolling stock.

The layout features a terminus station, a bus garage, traction engines and a goods yard. No layout can be considered complete unless there is a pond – yes Maxwell has one too!


Using boards ‘rescued’ from the Channel 5 Great Model Railway Challenge, this 7mm layout is modelling an extensive harbour scene complete with equipment to load coal from wagons onto small cargo vessels. in the background will be a low relief model of dockside warehouses.

The trackwork will be controlled from a small signal box with its own working mimic panel inside the box.


Uffculme is a 3mm scale layout modelling a part of the English countryside. Whereas the focus on Purleigh was digital control, Uffculme is all about fine scale detailed modelling of a traditional English rural scheme.

When complete, this layout will be able to be used in conjunction with other CMRS layouts.

The society organises demonstrations and workshops on Wednesday evening to introduce new modelling techniques or to develop new skills. For the last two years, the monthly electronics workshops have helped members make use of new technologies to help them operate their layout. The forthcoming workshops are listed in the Events tab.

In addition to the layouts under construction, there is a test track where members can try out their own rolling stock under DC or DCC control. One 2mm, two 4mm and one 7mm track are available.

The Layout tab shows the Society layouts and some layouts that are owned by some members of the society. You may be interested in the Under Construction section which provides more infirmation on the progress and challenges being faced on our new layouts.

We are alway glad to welcome new members at our South Croydon clubroom.
