Code 55

Use SL-310 metal joiners and SL-1208 joining sleepers. Use SL-311 insulating joiners to create isolated track sections (if using DCC control these are not required).

One of the great advantages of TT:120 is that the 12mm gauge track correctly scales out as standard (4' 8.5") gauge, as used all over Britain's railway network. The ingenious rail section of PECO code 55 combines strength and durability with a highly realistic appearance – In TT:120 the visible height of the rail correctly represents 113lb flat bottom rail. The flexible sleeper base is detailed with fine wood grain and spikes through British Railways’ BR1 baseplates under the rails, a combination that continues to be widely used on Britain’s railways.

1 set of Turnout Blades and Brackets for the construction of turnouts, using Code 200 Flat Bottom rail. Gauge One models are built to a scale of 10mm/foot, or approx 1:30 scale. This is a great scale for live steam locomotives, or electric and internal combustion models. This scale is often used in the great outdoors, however, indoor scenic layouts are not unknown.

83 Line items are realistic models of North American railroad track, with Code 83 nickel silver rail. Scaled from A.R.E.A. drawings and NMRA compliant, Code 83 features authentic tie sizes and spacing, the standard American number system for frog geometry, plus a very fine representation of traditional rail spike fixings. For more details on Electrofrog turnouts, see our Wiring the Layout publications Nos 4 and 21.

These turnouts emulate the modern style of concrete sleepered trackwork which features Pandrol (TM) style rail fixings. Concrete sleepered turnouts had previously been impractical due to the concrete being broken by the impact caused as wheels passed through the frog area. This has been resolved by redesigning the frog so that the flange supports the wheel across the gap in the running rail.
