RE:RE:Four (4) more trains delivered in Switzerland This is very good news (esp. if they keep BT). I know a little bit about this stuff. Basically it means the design was sound and given the kitchen sink nature of the design, speaks well for BTs Engineering team. //
.
My guess is they probably rushed it to meet contractual obligations (BT seems to have a sales/bid problem - taking deals they shouldn't, promising dates and functionality they shouldn't be, in order to win contracts), some manufacturing issues, some software issues, designs that had to be amended. // .
Which is infinitely better than having a design that is fundamentally flawed and cannot - regardless of the amount of duct tape and the most talented MacGyver - be fixed. THAT would be a real nightmare.
