Apologies for posting what is a relatively technical question that some users will not understand, if I can explain any further just ask and I will try.

In Western Region E10k interlocking, which has no Train Operated Route Release function, once a route has been used, it will remain set and locked, but the first route light will flash, to remind the signalman that he needs to cancel it off. This happens on both Turn-push, and Push-push panels.

When Reading Panel closed and was demolished, some of its remote E10k interlockings were retained, driven off the IECC system in the Thames Valley Signalling Centre at Didcot, off new TDM systems without the PO3000 relays at the box end, which were replaced by computers.

My question is, does anyone know what indications the Signalman receives on the IECC screens when the route has been used but not yet cancelled off? Or, does the IECC somehow apply TORR principles?

EDIT: Another question, is the lock light replicated for points?

The IECC applies TORR through the RIIU. This is quite common - I recall Leeds having numerous different relay interlocking types, each requiring different techniques for TORR, not just route setting.

Not sure about the points: I wouldn't have thought so as it's not something other interlockings provide so it wouldn't be consistent across the screens were it to be provided. I await to be corrected though!

If I recall correctly not all of them do but there are numerous lock lights in the Theale interlocking.

There are only lock lights on points that lock after a time, or release after a time, and not all of those in any case.

There is no direct replication of the locked lights on all points such as that that existed on the panel.

Oh and I forgot to add that the subsidiary routes do not TORR. There is no flashing segment to indicate that the route is used.

I wonder if this is something new as I'm seeing this in brand new installations too.

That is interesting as E10k uses the same route calling relays for whatever class of route is ultimately selected, and I remember reading somewhere (http://www.rgsonline.co.uk/Deviations/Derogation/09-106-DGN.pdf) that this was still the case when the controls were moved to Didcot.

It does seem rather strange to have one class or route TORR but not another, especially from the same signal.

Danny, do the overlaps for the signals now illuminate when a route is set up to them as well?

Funny you should mention that. Last time I was testing at TVSC I didn't spot anything unusual and I'd forgotten that E10k don't illuminate the overlaps. Therefore I'm fairly certain that overlaps at TVSC do illuminate.

In fact, Danny's photos confirm it Newbury
