Peco SL-U1294 TT code 55 long crossing

Streamline ranges incorperate flexible lengths of track which can be manipulated to form far more geometric options, but represents a need for more expertise in both layout building and track planning.

Code 55 (rail height of 0.055") is a finescale standard for TT Gauge model railway. Because it utilizes the same joiners as code 80 in Peco's range, it can be used to expand on Hornby's range of TT Gauge railways (which is code 80), although the appearance between the 2 systems are slightly different.
