New signalling items (perhaps) at Farringdon and St Pancras

Unread postby JG Morgan » Thu May 11, 2017 4:58 pm

This week I have noticed some new objects between the tracks of the Thameslink platforms at St Pancras and Farringdon. It's hard to tell what they are as they are still covered with black bags. But they may be signalling related, hence asking on this Forum.

At St Pancras, these are about three coach lengths north from the south end of the platforms. There are three objects, a few yards apart. The outer two appear to have a flat face, perpendicular to the tracks (so probably a sign for drivers), and are about 2 feet tall, bolted to a square concrete plinth. The centre object is about the size of a ground signal - but there are no points nearby so that seems unlikely.

At Farringdon there is just one object, at the extreme south end of the platform - so less easy to see without attracting suspicion.

At both locations, there is wooden shielding along the third rail for a few yards - presumably to give some protection to maintenance staff.

Any ideas?

A photo would help if at all possible. Is it related to the Thameslink 'core' TBTC/moving block resignalling, I wonder?
ND: Why is there a door handle on the inside of my airing cupboard?
MF: Because it's the fire exit from Narnia.

I like David Lynch films. I don't consider incomprehension to be a barrier to enjoyment.

Are these items the same as TFL recent years installed on the Met line for introduction of S stock.From a distance they look like signals but were connected with the train drivers CCTV and door release.

Nothing fancy, just 'Block Marker ; signage. (yellow triangle pointing towards line it applies on blue background) that will be used when ETCS is introduced.

Thanks for your replies.
These are not the same as those shown at http://www.railsigns.uk/photos/p_cabsig ... ic_blockm2, (those at Farringdon and STP are of the order of 2 feet high) but they could be miniature versions of the same thing, reduced in size to fit in the restricted space on the Thameslink Core.

Taking a photograph last week would have shown size only, but no more, as they were covered with black bags. I didn't see as many at either Farringdon or STP as the diagram suggest. I didn't look this morning (as I was talking to my boss), but will look tomorrow or later this week if I remember.
