PECO Streamline Flat Bottom O Gauge track is superbly detailed, with correct scale width 'wood grain' sleepers and integrally moulded baseplates with Pandrol (TM) type rail fixings. Insulated rail joiners are required to provide electrical breaks where Electrofrog turnouts are used, for more details see our Wiring the Layout publications Nos 4 and 21. The SL713 Transition Track is an ideal way to connect Flat Bottom track to the Bullhead Setrack and Streamline track systems.
