I think that I have posted here about a journey on Eurostar (pre-HS1). Somehow a SouthEastern train for Hastings had got in front of the Eurostar at Chislehurst Junction. First, the Eurostar waited at Dunton Green, while the Hastings train made its stop at Sevenoaks (presumably with exit route set), then, again, we waited on the curve just short of Tonbridge, with the signal set green across all four routes to Hastings, I could see it clearly.

Result, missed path at the tunnel mouth, and twenty minutes late at Brussels, and two hours late to Koeln. In those days, you could not use a Thalys ticket on ICE.

So, how early does a route need to be set?

I charged lazy signallers, over-reliant on ARS, but the experts on this forum had some excuse!

Sounds like a deliberate regulating decision to me, rather than setting a route early in error or laziness.

Depends on the line, service etc. At Bedford we will clear the Bedford-Bletchley service as soon as it arrives, because we know there will be no conflicting moves. Thameslink services are cleared as soon as we get the TRTS and not before. East Midlands southbound services are generally routed straight through the platforms as soon as they appear on the panel at Sharnbrook in quiet periods. At busy times I wait until two minutes before departure.

Depending on what panel I'm working at Rugby SCC has a lot to do with when I pull off for a train.

Bletchley towards Bedford, as soon as the train arrives route it back towards Marston Vale, likewise at Nuneaton towards Coventry

Northampton, depends what mood I'm in, normally well before departure time, but in times of disruption I'll adhere to the Sectional Appendix to the letter and get them to press the TRTS

Rugby early doors, normally I've got routes in for trains 40 minutes in advance on some routes.

Really, it's all at the signalmans discretion, set early enough based on the information available, but without "snookering" ones self

Thanks everyone for providing all these examples that really make the issue clear.

Back to back radios have their advantages, but at the same time have their disadvantages.

I saw them get almost permanently switched off in one signal box after the Signallers got quickly fed up with being distracted by totally irrelevant discussions between Platform Staff about things which did not matter, and missing the things which did matter because they had subconciously tuned out the radios anyway.

As an S&T man, if I am working close to a box I will almost always drop a radio up to the Signalman as we find they are a lot easier than using telephones.
