lymigton branch

[341o2]

I've noted 3 recent occasions where a 450 has worked the branch weekdays. Is the branch now worked by a 450 and the 158's have been displaced? Any info appreciated

Has been operated by a 450 during the Olympics to release the normal 158 to operate Bournemouth - Weymouth extras.

SWT are deferring small maintenance jobs to increase the number of units available so there are a few extra 450s available, it wont last past the olympics because then they will be playing catch up before the paralympics start.

Forgive my pedantry, but would it not make more sense to use the additional 4 car 450 on the Olympic extras rather than a 2 car 158? Seems a very bizarre way of doing things, is that for definite? I would have thought that strengthening the diesel services out of Waterloo might have been a more sensible option?

As mentioned in about a dozen different discussions so far, there are power supply restrictions at the far end of the Weymouth line. Using a couple of 5 car 158/159 combinations to augment the service beyond Bournemouth means that they can run extras without worrying about third rail overloads...

Ah, that would explain it then! I'd missed those other conversations, thanks for that info

A few 8 and 12 car 450s have visited Weymouth over the Olympics with special permission from Network Rail.

However, as a result of the power supply on the line to Weymouth, which was electrified in the late 1980s and the single track section on part of the route, the number and length of trains that run on this route are limited. We have worked in partnership with Network Rail to enable the maximum number of trains to operate during the Games, and to enable key trains to be strengthened by drawing extra power for this limited period.

Indeed. I think I have also quoted that piece from SWT in one of the other threads...

They've got a couple of 8-cars booked to/from Weymouth each day, but no 12-cars. They definitely would overload the third rail.

 

[GearJammer]

Can they not run 12 car 450's to Weymouth but only have 2 of the 3 units taking power, or is that not technically possible?

There was definitely a 12-car to Weymouth on the first Sunday.

When the 8 coach trains have run to Weymouth every electrical substation has been manned with NR staff in case of problems, not a very efficient use of staff.

the 12 coach one ran at times when it would be the only train drawing power.

Was that one heading to Weymouth? Because IIRC it would split at Southampton with the front 8 running to Weymouth.
