Over the last few weeks I've noticed new signs go up presumably for when using TBTC.
I'm guessing "RM Hold" is for when running in Restricted Manual? Is it an instruction to hold at that sign and seek additional authorisation before proceeding, as one would at present when held at a semi-auto?
What does the "EP" sign mean?
I've also seen new three-letter site-codes for the signs, for example, I think from memory, WIL for Willesden Green.

According to an LURS talk I wrote up for them, any signage connected with the Jubilee upgrade is hexagonal, so if it was, it's to do with the upgrade.

According to my training book.
EP stands for Entry point = Indentifies the location of the boundary between 2 TBTC loops.

And IIRC from my TBTC training, drivers in Restricted Manual will need to stop at RM Hold boards and contact the signal, proceeding only with authorisation - this is as there are no fixed signals, so no designated point to agree for a train to continue to - (except for a platform, obviously).

Are there designated berthing points? For those of you of a signalling bent I'm *not* thinking of a TBTC Lime St. Control. (fixed length units, anyhow). |

Most RM hold boards on the platforms are where a station starter would usually be so the train fully berths.

How are repeaters going to be handled so that station staff when giving an assisted dispatch know when the train is ready to depart?

A white light is located on the platform and when it's lit tells the station staff the train has received a target speed and will depart shortly.
Staff are told if no light has illuminated then go and speak to the driver.
Personally I'd have liked a Central Line style "Mind the Doors" message played on the DMI additionally to act as a signal to platform staff.

Is it an instruction to hold at that sign and seek additional authorisation before proceeding, as one would at present when held at a semi-auto? The rules around it are very much like how you'd treat being held at a semi-auto, yes. When a train is in RM, it does not have an exact location for it up at Neasden as it is not under the protection of the system and the only way they know the train is where it is is through the axle-counters. What the Stig said, but just to elaborate also, if the train's on-board signalling equipment is having problems or needs to be reset, they need to be done so before they go past this board. I think the only time this would happen is if you've had a problem and had to drive in PM or RM at any point up to an EP board. This is both for the benefit of the system at the new version of Trackernet. Not sure whether this is because they plan to hopefully get all station control rooms onto the new MICA system – at the present time, we've got all sorts of three-letter site-codes with SIMS. A white light is located on the platform and when it's lit tells the station staff the train has received a target speed and will depart shortly. The current nightmare at the moment (with the trial ops anyway) is that the light comes on both in the instance you've stated and also when 'HOLD' has appeared on the Train Operator's Display. Does the DMI message on the Central line only come on once that train is ready to proceed or is it after a certain time? Oh – and for anybody here who's never seen an RM Hold board, they look like this (though not falling apart on the floor):  They have repeater boards and they are marked with yellow hexagons as opposed to red. |

Do these relate to the RM signs that I see on the techs terminal |
