THE SIG­NALS

Model Rail (UK) - - Layout Hatch End -

Heath­cote Elec­tron­ics’ IRDOT (In­fra Red De­tec­tion Of Trains) sys­tem plays an im­por­tant role on ‘Hatch End’. One of its mass-se­quencers, com­plete with timers, auto-se­quences the Roger Mur­ray sig­nals. An­other nice fea­ture is the blue flash from a gantry mast to rep­re­sent an arc flash from the pan­to­graph. This, too, is trig­gered by a Heath­cote Elec­tron­ics IRDOT in the track. Mov­ing to the back of the lay­out, we have 18 sid­ings, and each one is fit­ted with a tiny LED from Mi­cro Minia­tures. This helps to tell us if a train is on the move and that the points have switched over cor­rectly, as it’s dif­fi­cult to see the points at the far end of the lay­out.
