RT I meant some of the relays that are only associated with the floodgates would have remained in the same position since the floodgates were last tested. Many years ago I went into one of these rooms and I am sure there was also another room which could not be accessed but looking through the window of the door it appeared as some sort of electrical equipment and I was already with the floodgate equipment. I believe the 'another room' was one of those that either lead on from the IMR via a usually locked door, or are sited elsewhere, such as in the original C&SLRly passenger tunnel at Stockwell. My experience is that these often contain the higher voltage (some at 60v) equipment that is associated with the signalling / IMR, such as rectifiers, transformers and a range of other electrical equipment. There may also be some other equipment there as well, such as switches etc. Yes the IMR power room which contains the 600v ac CBs, signalling supply changeover switches, 600/100 step down transformers, P/MC batteries, telephone direct line PSUs and/or standby batteries or 24v battery strings and of course various fuses and 240v domestic supply auto changeover contactors. I rarely if ever thought of the power room as a separate room, even though it was, as generally it was all the IMR and invariably just the other side of a wall. Platform relay rooms were often similarly divided into two rooms many with a partial partition rather than a separating door.

I also think now that there was separation of rooms so as to keep certain circuitry separate.

RT yes I can think of lots of locations that had a power room but everyone still called it part of the IMR.
