Hi all
In between East Acton and North Acton there is a bridge over the central line near a large building that now appears derelict - I remember as boy some er (cough cough) 40 years years ago being able to walk across it,the access being from Old Oak Lane, I recall being able to get all the way to Victoria Road - the question I have is that even though I must have passed very close to this building I knew nothing about, until Google Earth came about, does anyone know what its use was ?

Hi all In between East Acton and North Acton there is a bridge over the central line near a large building that now appears derelict - I remember as boy some er (cough cough) 40 years years ago being able to walk across it,the access being from Old Oak Lane, I recall being able to get all the way to Victoria Road - the question I have is that even though I must have passed very close to this building I knew nothing about, until Google Earth came about, does anyone know what its use was ? The former Old Oak Common Substation, which was replaced in the 1990s by a new substation at Park Royal as part of the Central Line modernisation. I believe the building no longer has any function, although I think the site is still used as a cable route by the HT cables from Acton Lane Bulk Supply Point, which feeds the western tip of the Central Line. |

The mystery building were built by the GWR at the beginning of the 20th century certainly before WW1. In my time as the BR Paddington High Voltage supervisor in the 1980's the intake was from Acton Lane CEGB 2 circuits at 22,000v the feed running along from the Grand Union Canal along Old Oak Common Lane there was a third circuit from Horn Lane but it was disused in my time.
The CEGB 22kV switch room, which is the Western most building supplied LUL at 22kV the LUL 22kV switch room is at the north eastern corner of the main building.
BR was sub supplied by LUL at 6.6kV there being 3 6MW 22/6.6kV transformers as part of the CEGB building. BR had a Main Switch Room on the north side of the main building which was designated as sub station "C" from there we had 2 main rings one feeding Old Oak Common TMD there were at the time 5 subs B1 to B5 feeding all the domestic, yard lighting and 850v & 415v train heating shore supplies.
The second ring ran from S/S C along the main line to Royal Oak S/S G with intermediate S/S at OOC signal box S/S R, Kensal Rise S/S D, Westbourne Park S/S F & H, from Royal Oak there was (still is) two rings feeding Paddington Station Plat 1 S/S K, under plat 4 & 5 S/S L, Under GW Hotel S/S M, under plat 1 booking office S/SN and under plat 10 S/S O. There was also a ring via the old goods yard S/S J1 & J2 which then went to S/S M via O but that all got altered when the good were demolished.
Originally the GWR had a power station at Park Royal with S/S A close by, this power station ceased in the 1950's as it was only used to supplement the peak loads. The GWR system was built to power OOC TMD and Padiington Station but also the H & C line there were S/S feed from OOC sub at Hammersmith, Shepards Bush and Royal Oak the GWR / BR manning and maintaining these untill the late 60 or even early 70's
BR ceased taking a supply from OOC S/S C in the late 80's the 6.6kV cable route had to be moved from the south side of the main line to accommodate North Pole Depot also BR needed a 22kV supply into North Pole for DC traction (the other intake for the North Pole system is Queens Road Battersea where there is 33/22kV transformer take from the Net Rail system)
Today Paddington has a direct feed taken in at Royal Oak at 6.6kV and OOC has feed via 11/6.6kV transformers within the TMD the ring between has been removed this was in part due to system demands at Paddington and the reliability of the ring cables between Padd and OOC.

I had a small involvement in the transfer of Old Oak Common to Park Royal. My part was to design, install and commission temporary tunnel telephone equipment in the new Park Royal substation, run new tunnel telephone cables from White City via the track parallelling hut at East Acton to Park Royal, over and back changeover, commission, test, and decommission. It sounds odd but Old Oak Common was the feed end of the T/T circuits from Wood Lane substation and moving that end westwards meant that I lengthened the T/T circuits by several thousand metres..
At the time available T/T equipment was as rare as hen's teeth, in fact the only available rack was the decommissioned Bakerloo Stanmore branch T/T rack in Baker Street substation which was still connected and powered as the new Jubilee T/T racks power cabling had been looped off it. I can still recall the night during the week that I went into Baker St. SS to remove the rack. It was a complex operation, not so much rewiring power supplies to affected equipment but the fact that I had to test 14 T/T circuits on three lines which meant dealing with three Line Controllers one after the other prior to the commencement of traffic. Also manhandling the rack out of Baker St. was tricky.
I recall Old Oak Common SS as a quaint place old brick building and its T/T equipment was very old dating from a time when it would have been manned. The new SS at Park Royal in contrast was prefabricated in four portable units and bolted together and totally modern within with nice neat cubicles and equipment except for the ropey old rack that I had installed! However, that was replaced by the Central Line Project team with a nice new Westinghouse T/T cubicle once Old Oak Common was closed and Park Royal was commissioned.
As for BR substation 'K' I am also familiar with that as I had to pay a visit to it when I was doing the Crossrail surveys of impacted LU areas at Paddington a couple of years or so later.
