Class 333

Just a quick one.

Have these ever worked doubled up? I'm guessing they can work this way but i haven't ever seen it.

I've never heard of it nor seen it. It may well have happened but it doesn't happen regularly. Presume passenger numbers aren't high enough and platform lengths at Shipley P2, 4 and 5, and numerous other stations on the route.

Are they not the same as 332s which often work in multiple on HEX services?

I was under the impression that they used to double-up some ECS movements in order to maintain driver competence in coupling and uncoupling. Is that still the case...?

They could not work doubled up on a passenger service on any line in the Shipley triangle because of the platform lengths.

In many years of travelling on the route, never seen them running in pairs on ECS or training moves. Practising coupling could easily be done at Skipton or Neville Hill without need for actually double running and the timetables are such that there are few to no ECS moves anyway.

I hadn't thought about the platform lengths. Duhhhh

Although rare i have seen them come from Neville Hill into Leeds doubled up. On one occasion they had both pans up.

There are regular ECS moves out of Skipton in the morning for pairs of 333s, although the rear unit is dragged dead as Northern don't have a safety case for operating pairs of 333s with both pans' up and taking power.

The last time I saw two working in multiple was when they were being delivered.

I've been on a train with a pair - 008 and 014.

As previous posters have said, platform lengths don't permit 8 car operation. In this case 014 was locked out and unpowered. It must have failed at Forster Square but was being dragged by 008, as I got on at Frizinghall.

It's the only time I've seen it happen in 12 years of fairly regular Aire Valley travel and - of more interest to me - dragging a dead unit didn't slow the powering unit down much. I know the performance characteristics and it wasn't good, but not bad enough to alarm the normals.

Out of interest, what could a 333 couple on to, aside from a sister unit.

Nought, not in such a way that both units could "communicate" with each other, anyway: I don't think that they are even fully compatible with 332s.

That would have to be a heck of an off-region working

Drags are almost certainly due to the available power on the Airedale electrification. Two units drawing power in the same section may cause an overload where it is perfectly acceptable at Leeds due to the higher current available to permit LHCS operation.

I don't doubt that could well have had a part to play, but since the electrification was "beefed up" enough to allow the 91's to run without bringing everything to a grinding halt in the area, what is the likelyhood of two 333's still causing issues?

shedman · 3 Dec 2012

I asked Siemens this very question only last week when I moved a pair. They can work together but as mentioned there is no safety case to allow it. In fact one of the reasons I was moving them together is because they had done repairs to a "non multi" and were checking everything worked fine
