Flexible Track, Wooden Sleeper. Peco Streamline Code 75 track meets the standards of enthusiasts who prefer to run trains on scale height rail. Today most manufacturers' wheels are suitable for use on Code 75 track but some vintage models may have flanges which are too deep to clear the rail fixings. Code 75 can be easily combined with code 100 track by using the SL-113 Transition Track. 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.
