Mis-formed SWT 158/159s

[capital12]

There seem to be a few mis-formed 158/159s running around in SWT land at the moment - possibly down to damage from weather related incidents and/or maintenance?!

Today 159016 was seen with 57889 from 159017 forming the rear coach, in lieu of 57888.

Seen on Saturday was half each of 158883 & 158885 forming one unit, although wasn't able to get coach numbers.

Was thinking one location for any sightings would be more helpful though as that thread is more about unusual locations?

Just a thought but if they have switched coaches around, for whatever reason, aren't they more likely to remain that way rather than get switched back at a later date?

Or are these coaches of different types?

(unit numbers mean little to me beyond the class number)

Aha, Thanks for clearing that one up. I saw it whilst waiting at Basingstoke for a Salisbury bound service the other day and thought that was a little odd. Still yet to see the infamous 159108 through Basingstoke yet though - perhaps it's being kept on the Salisbury 6 diagrams?

I think they're the same kind of vehicle. Vehicle numbers usually (well on DMUs at least) have a pattern, so in the case of 158/159 end vehicles are 57xxx and 52xxx.

Whether SWT will return the vehicles to the correct formation I'm not sure, but certainly operators where the vehicle numbers match the unit numbers (ie 158xxx from above) always seem to do so.

They usually do change them back. The bulk of maintenance is time or mileage based, so you really want to keep the original triples or pairs together so that the maintenance is not done too early or too late on odd vehicles.

Technically short formed rather than mis-formed - 159106 was seen this morning minus it's centre coach and was in place of a 158 on the 10 coach arrival at Waterloo at 0814.

Spot on.
