Track crossing Double Junction Crossing (TJD) code 75 Peco SL190 Insulfrog with a length of 249 mm, an angle of 12°.
The TJD is a crossing that allows you to change track like a switch.
The track change can be made on both sides as long as a Peco SL180 Single Junction Crossing (TJS) allows the track to be changed on one side only.
To motorise a TJS or TJD, two motors are required.
The Peco brand of track offers a wide range of track for building a model railway layout.
The British company is known for its rails in code 100 and 75 in HO 1/87th scale.
The track sections are made from maillechort (an alloy of copper and brass), materials that offer very high electrical conductivity and do not oxidise (easier cleaning of the rails).
Peco's 1/87th scale HO turnouts are available in two technologies:Insulfrog and Electrofrog.
The Insulfrog models have a plastic core point (and therefore not electrically powered). These turnouts are recommended for model railway systems in analogue operation (conventional power supply via a transformer).
The Electrofrog models have a metallic core point (allowing better current pick-up from the locomotives). As a result, at low speeds, the locomotives run more smoothly. These turnouts are recommended for model train networks in digital operation (power supply by digital control unit).
The points deflection system allows the turnout to be motorised with several types of motor:
A table-top motor reference Peco PL11 which is placed next to the turnout on the track plan.
An under-table motor reference Peco PL1000/PL1001 which is placed below the layout support for discreet installation.
Peco straight turnouts in HO 1/87th scale come in three lengths: short, medium and long.
