The Formation Of A Class 707 Train

South Western Railway are starting to use more Class 707 trains.

Wikipedia does not give any details on the formation of the trains.

This morning, I rode an example out of Waterloo to Clapham Junction. So I decided to ascertain the formation, by reading the designations on the ends of the carriage.

  • DMSO – Driving Motor Standard Open
  • TSO  – Trailer Standard Open
  • TSO(L)W  – Trailer Standard Open with provision for a lavatory and a wheelchair space.
  • (P)TSO  – Trailer Standard Open with provision for a pantograph.
  • DMSO – Driving Motor Standard Open

Wikipedia has a list of British Rail coach designations.

Note.

  1. The Class 707 train has two motor cars and three trailer cars in the middle.
  2. The train is wired for a pantograph and has already been tested with one.
  3. I suspect because of the designation, that a lavatory can be added.

I have been told that the Class 720 trains for Greater Anglia, which like the Class 707 trains are 100 mph five-car trains, have traction motors on every car.

I suspect that this gives faster acceleration and smooth regenerative braking.

But because there are more traction motors, the trains must be more expensive.

So have the Class 707 trains been designed down to a price?
