Electromechanical automation

[Nick RidgwayParticipant]

Some years ago I created an automatic OO gauge layout entitled Little Dublow – long since dismantled.

One of my next projects is an EM gauge replacement, entitled Coggeshall/Silfield Road. . I’m using a 3-channel Herkat  track occupancy relay and a proprietary multi-function timer.

I’ll put some stuff in the Newsletter at some point.

Update: I decided I can do without the Herkat.

I’m now using a proprietary multifunction timer set to 36sec. The timer operates a relay that reversed the traction power polarity, and the motive unit stops on a diode-protected track section (I used the same technique on Little Dublow).

Track down; let testing commence!

Nick,

This sounds fascinating! Will the electronics accelerate and decelerate the trains as they leave/enter the stations as well?

I’m not that clever.

I suspect you probably are if you really put your mind to it… 😊

I’m sure he is, though this is all way beyond my understanding…

Update: Coggeshall Automatic made its debut at the Mid Essex show in Shenfield in September 2023, as part of the EMGS Demo stand, where it proved that one can always find space for a model railway, even if it is above a computer workstation. The Exhibition Manager remarked with a smile, “I don’t remember booking that!”. I pointed out that he wasn’t paying for it either.

It is available to annoy others at other demo stands as required. 🙂
