“Policeman” trainstops at through stations

[goldenarrow]

Always wanted to ask about the trainstops situated halfway down the EB platform at Euston Square and Embankment WB which are “blind” as they appear to operate without an accompanying signal.

I have never seen an instance where a train has been checked by one of these as an Approach/Moorgate control scenario. I also can’t recall seeing the one at Euston Square before 2015 as I took an extensive set of photos of the station at the time and can’t see them.

Just for reference, here's a photo by @bowroaduk showing the trainspot set further back from the tripcock tester.

They are there to protect the floodgate at Embankment.

As the floodgate has been decommissioned for sometime now they could of been removed but it was cheaper to leave it in at Embankment.

I can’t speak for Euston Square but I believe a tripcock tester was installed around that time sure it wasn’t one of these as opposed to a Trainstop

Euston Square was provided at Christmas 2015 to protect a train detained at the new scissors crossover west of King's Cross. If a train approaches too fast then it will not lower.

We have a resident expert who can almost certainly tell you everything you need to know about Euston Square in particular... 😉

Guilty as charged! I'm actually responsible for naming it too, the original design scheme was going to call it 200V. I pointed out that this was a draw-up trainstop so should be identified as if a draw-up signal, plus there was already a 200V about 100m along the track on the other road which would confuse maintainers, hence it was named 2010V.

It was commissioned ready for Start of Traffic on 31/12/15, though I ended up testing it one afternoon a few days earlier, the 29th from memory. It acts in exactly the same way as a draw-up signal, but without the signal. The signal sighting committee at that time felt a blind trainstop was preferable to a normally red signal mid-way along the platform.

The tripcock testers had been provided since (at least) the mid-1980s resignalling.

We have plenty of blind trainstops on the Picc. Halfway along platform 4 at Arnos Grove for trains coming in from the EB road, halfway along sidings at Wood Green, all 4 Acton Town sidings, Rayners Lane sidings, both Heathrow T5 sidings, one halfway between Acton Town and South Ealing on the WB fast road (believe this goes back to the days when it was the test track), two thirds of the way down the platform at Leicester Square EB to protect the short overlap, all platforms at Cockfosters and Uxbridge. I think that's it!

There's a normally red signal about halfway down the City-bound Metropolitan platform (3) at Baker Street; I can't remember if there's an accompanying train stop or not.

It used to.confuse a fair few passengers as many a train would slow to a crawl before continuing, sometimes at a fair pace, to the end of the platform. I presume this was because of a combination of the tight bend on the platform/track and the approach to the (Outer) Circle track and junction?

I'm sure I recall another similar signal, but can't remember where it might be. Any ideas?

That's MB140. It protects a short overlap to the junction. It can clear one of two ways, sometimes you can pass it faster than others depending on how the driver approaches.
(There used to be a third method but that was removed after someone stopped a battery loco in the wrong place and locked the site up.)

Both Baker 3 and Baker 5 have such signals to protect the junction, and there's train stops with both.

Edgware Road formerly had draw ups, and there's plenty of other examples across the Combine.

Earls Court and Whitechapel has them on the District

There used to be a signal tucked under the westbound Central Line platform, about a quarter of the way down, at Liverpool St. Almost caught me out a couple of times.
