d00m Posted September 14, 2019 Share Posted September 14, 2019 Has anyone on here modeled these and/or mechanical signalling ramps? They are (with ATO being introduced) an endangered species and may need photographing before they are all gone. A trip to the pic with camera may be in order.

Broadway Clive Posted September 14, 2019 Share Posted September 14, 2019 Steve Smith has train stops (non operational!) on his London Road layout, which is based on the Neasden area of the Met where he works. He's modeled a great deal of LT signal infrastructure, often producing parts for himself in resin. I was privileged to assist in operating it at the Romford exhibition for the last couple of years but thats been cancelled this year as the local club's membership has declined and aged.

Edwin_m Posted September 14, 2019 Share Posted September 14, 2019 Just to clarify, there's one there for each direction I think. Link to post Share on other sites More sharing options...

bécasse Posted September 16, 2019 Share Posted September 16, 2019 And don't forget, with the old traditional LT signalling (although it predated even the formation of the LPTB) a red aspect indicated "train stop up, do not proceed" whereas a green aspect indicated "section ahead clear, proceed unless the red aspect is illuminated". As the lowering of the train stop was a mechanical process, there were always a couple of seconds when both aspects were alight. Link to post Share on other sites More sharing options...
Edwin_m Posted September 16, 2019 Share Posted September 16, 2019 And presumably if the train stop failed to prove down, both aspects would be lit indefinitely. Link to post Share on other sites More sharing options...
RMweb Premium CloggyDog Posted October 23, 2019 RMweb Premium Share Posted October 23, 2019 I scratchbuilt some 4mm ones recently for a friend's LT micro layout. As a terminus, I made them double-ramped. 2 x 15mm lengths of Evergreen 3.2mm channel glued open face to open face, ramps from Evergreen O Gauge 'car siding', 3 plank widths x 1cm, some 10 thou microstrip strapping on top and the train stop arm itself from microstrip (sorry, can't remember the size) Ramps painted burnt umber, trainstops light grey, arm white. The paintwork has been touched up since those were taken. 4 Link to post Share on other sites More sharing options...

Yes. Actually quite an important indication as it effectively told a driver to "trip past" the signal (ie pass the signal, then stop and reset the trip which could only be done outside the cab) and that the section ahead would be clear - he/she was still required to proceed slowly though, prepared to stop short of any obstruction.

Lord of Narnia Posted February 1, 2020 Share Posted February 1, 2020 These train stops look great. I scratch built one as a test and it’s well worth doing. Not too difficult either. Modern trains have SCAT (speed control after tripping) to automatically limit the train speed after a deliberate tripping in such an instance.
