I had to opportunity to take a quick look at the new Soham station this morning.

The station is on the single line, immediately north of the points at the start of the double track section towards Ipswich. And by "immediately", I mean that CA494, which protects the junction in the Up (towards Ipswich) direction is at the end of the platform and less than 5 metres from the toe of the (facing) points. (For those not familiar with the area, there's a single track from Ely to Soham and then double track to Chippenham Junction, near Newmarket. No sidings or trap points or anything like that between Ely and much closer to CJ.)

A train to Ipswich was due shortly after I got there, so I waited. Even though the points were set correctly, CA494 stayed red until the train was almost stopped, before it went green. I asked the driver whether this was usual and he said yes. I asked if he thought it was the bobby or built-in and he said it was always the same, so he thought it was built in.

I can't understand the reason behind this. CA494's overlap will extend well over the points, so it's not providing any useful protection. I can't believe that through goods trains are brought almost to a halt here, so that implies the signaller can turn the approach control on and off.

Any thoughts, anyone?

Could there be a crossing with stopping/non-stopping controls shortly afterwards?
There's the right way, the wrong way and the railway.

That would make sense, for Mill Drove AHBC just up the line. https://www.google.com/maps/@52.3287644,0.3299067,3a,75y,342.16h,73.33t/data=!3m6!1e1!3m4!1sKfRSHOFAjOmcFYBLhjZCaQ!2e0!7i13312!8i6656

Hi,

To confirm - I was there helping with the PR during the opening of it and a fair few freight trains pass through at linespeed, so they're not held at red.

CA494 has a stopping/non-stopping control because of Mill Drove AHBC, around 650m Ipswich side of the station.
The signal defaults to (an unnecessarily restrictive) stopping mode unless the signaller selects the non-stopping button.

Thanks. I should have thought of that. There didn't used to be one but, of course, there didn't used to be a station to stop at.

Thanks. I take it that's a turn switch rather than a push button? (IIRC, the other ones on the panel are push buttons.)
