This Earl Class Dukedog (DCC Sound fitted) is a recent addition to my collection together with the Hornby GWR Clestory coaching stock.
Helm's Deep Model Railway features a DCC controlled 'OO' scale railway, the layout is approximately 16.5 feet long, by 7.5 feet wide (large section) and 5.5 feet wide (smaller section)
the layout is made up of two MDF boards connected together by bridge sections.
the layout rests on two trestles approximately 3 feet high
Scenery and detail have yet to be added since the layout has just been erected from five years of storage and is now installed in a purpose built room.
the layout does feature fully interlocked three aspect colour light signalling together with position light shunt signals which are also interlocked.
DCC Concepts Cobalt point motors are employed together with points and signal lever controls via two lever frames.
Train detection is in addition incorporated (track circuits) via the use of more than 80 infrared detection points supplied by Heathcote Electronics.
Over 600 DPDT miniature relays are employed to control the Signalling, points and track circuiting supplied by Maplin Electronics.
