Reports of Gatwick Express alight at South Croydon. There were a couple of similar incidents on 442s earlier this year as well (Victoria?)
They need replacing badly.
Was their electrical equipment taken from an older class like that in the 455s?
Yep. Not sure exactly what was recycled, but it was taken from their predecessors on the LSW Mainline, the Class 432 4-REPs.
Gatwick Express services have now been withdrawn until further notice today.
Iirc the salvaged equipment was traction equipment, motors, and the associated control gear such as camshafts, contactors etc, as well as some minor stuff like AWS control gear, receivers, relay boxes.
The first 4REP builds were 1966/7 with a few in '74.
Nothing goes on forever...
Not quite sure where you got that info from.....
Services were suspended for a short time due to the disruption and congestion caused - a sensible move to free up track space. Once lines had reopened and disruption had eased - it resumed service.
Nothing to do with the stock involved in the incident - it was simply suspended to free up space.
I was lead to believe that the 4-REPs had the same traction equipment and bogies as a class 73. In case that seems incredible remember that one 4-REP would propel itself and two 4-TCs from Waterloo to Bournemouth. A class 33/1 (diesel loco) would then take one or two of the 4-TCs on to Weymouth. But don't tell DaFT as they want to believe that sort of thing is impossible (1966 to about 1980s/1990s was a long time ago !). The 4-TCs were unpowered Multiple Units that effectively could inter operate with most Southern EMUs (also 33/1s and 73s) and looked like them. So the 4-REP traction equipment was man enough to handle 12 coaches !. Now it does that spread into two 5 car MK3 coach EMUs (slightly longer coaches ?). But yes they have done 44 years service and I guess some component is breaking down ?.
Another picture, identifying the unit affected as 62946.
Peter, the 442s do indeed have EE546 traction motors the same as the EDs but they are normally aspirated whereas the 73s have T/M blowers. The control equipment on a REP was air/oil operated camshaft I think, similar to the 1957/63 stock, but the EDs had electric motor powered camshafts with more notches and there were two of them. So motors = same, power control = different.
