I have been trying to find out what the practice was/is for the positioning of coloured light signals when visibility is restricted. Specifically I am trying to model a junction station where due to an over road bridge and a curved platform, the starter signals cannot be seen from a distance. Now I know, and it is clear from the photos I have, that when semaphores were used, they simply had repeaters on very tall posts so that the signals could be seen from a distance.

However, my question is what is done when the signal is a colour light? Although it is a starter signal, it is on a main line which could have non-stopping trains.

I am making provision for another signal before the station which will include a distant signal, but even then, I presume that the driver of any train passing through the station would need to be aware of the state of the signal at the end of the platform well before he reached it.

I have seen one photo suggesting some sort of peculiar repeater light signal at the other end of the platform, but can not find any other reference or any detail.

So if anyone could shed light on this (sorry about the pun), I would be very grateful.

Thanks

Geoff

Hi - I think the signal you are looking for a called a banner repeater. It is a black horizontal bar on a white background when the associated signal is showing red or on, and a diagonal stripe when the signal is green or off. These are used on semaphore or coloured light signals that have restricted sighting. They used to be a physical bar that moved, but tend to be fibre optic these days.

Thanks for the info, Craig. I will try googling Banner Repeater to see if I can find any pictures.
