Semaphore Signals

Some help please - I have got to the point on 'my Grandsons' 00 layout where I want to set up some Semaphore Signals, but I have absolutely no idea on the rules positioning on them.

For example how should I site the signal on the outer (main line) track where the points can switch traffic to the inner loop, what type of signal would it need to be, also on the reverse - from inner to outer line?

Also some guidance what type of signalling and positioning would be used in a goods yard, circa 1950 would be much appreciated.

I hope to be building them from the Ratio range.

Are the points to switch traffic between the two loops 'Facing' or 'Trailing'? That is, can the train move forward with a choice of the two directions (facing) or does the train have to be reversed back over the points (trailing)?
If a facing point, then a junction signal with two arms is needed. If a trailing point then a 'ground' signal - which Ratio do not make working versions of, alas - is needed. You would also need a 'stop' signal before a trailing point to protect trains if the point was against it.

In a goods yard there would be a stop signal to allow trains back out onto the 'main line' but otherwise there would be very few, if any, signals. Most small goods yards used hand-operated points and hand-signals by shunters and guards to shunt trains about. It was only the larger mechanised yards which would have had significant signalling arrangements. You would also need a stop signal on the 'main' line before the goods yard exit to stop trains while a train is coming out of the goods yard.

I know you've mentioned your grandson's layout elsewhere on the forum, but cannot remember the details. If it is a portable layout, then I would caution you about using Ratio kits. They are all plastic, and from experience I can tell you that they are very prone to damage when a layout is being moved. They also will not stand up to over-eager little fingers. I would suggest that if the grandson is under the age of perhaps 8, then it may be better to buy the ready-made Hornby signals. They are a little overscale, but they are reasonably robust and have quite strong metal posts.

Hope the above is of help,

Thanks for that reminder, poliss. Should have thought of it myself.

Mike H - I take it you've got one set of facing points and one set of trailing points. In which case have a junction signal on each line before the points, if I've understood correctly.

By the way, your quote from my post hasn't come up in a box like my quote of poliss as you've probably lost part of the trailing {/quote} (but in square brackets) somewhere along the line - it took me about 20 posts before I got the hang of it!
