A while back I mentioned that I had been busy making a portable test track. Two have been built, one for Peter Clark (who conceived the idea), and this one.
The basis is a cheap aluminium snooker cue case. The innards are ripped out, and replaced with a baulk of timber, on which the track is laid.
the overall case dimensions are 34" long, 3" wide 2"mm high. the internal timber is 2 1/2" x 3/4".- length to suit.
Case open for business
I left the timber a bit short to give room for a 9V battery controller (Thektronics in my case), and a single length of track is glued in place. Job done.
For Peter's track, we made the infill board full length and double sided. Each track is wired to a standard power socket to allow a variety of controllers to be connected. For Peter the requirement was to have one side laid with 2mm FS standard gauge and a length of NN3, and the obverse laid with PECO N track and a length of Shinohara Code 40, also N.
There is plenty of space to fit other combinations- N one side, P4/EM the other.. do as you please.
The intrepid could fit other connectors for DCC or analogue power supply, switched via a DPDT for safety.....the options are limited only by your imagination.
