As with the Peco TT Streamline track system the setrack range uses the unique double-foot Code 55 rail for robustness, and also for the finer appearance of the track. This means that both Setrack and Streamline can be connected together. Peco have started with just the one radius, no. 2, at 310mm/12.2in., and the length of the medium radius Streamline turnout (SLU1295 and SLU1296) is the same as one standard and one small straight section.
