A banker writes:
According to DafT's press release today about the invitation to tender for 1,200 new Thameslink vehicles:
"Carriages will be joined together permanently to form a train and will stay this way in a 'fixed formation' for the rest of their working life. This will make the manufacturing process simpler and more economical, and allows the trains to work more reliably".
Shame then that these trains, although more economical to manufacture, will be relatively expensive to lease given the residual value risk associated with such an inflexible formation.
Poor old DafT, a little knowledge is a dangerous thing.
