Concrete sleeper track has been in use on the railways of Britain since around 1940, usually combined with wooden sleeper turnouts and crossings, and this track is a faithful representation of this design. If you wish to mix wheel standards on your 00/H0 layout, this is the trackage to choose. Code 100 rail allows flange depths up to 1.6mm which means that both vintage and current stock will run happily together. The wide range of turnouts and crossings in this series includes every type, and the geometry of this range has been cleverly designed to make it easy to build convenient, complex and aesthetically pleasing formations.
