Sorry - not sure exactly what they're called, but why is it only the SSL

through (like a bendy bus)?

Is there something on the Tube lines that stops this design being practical?

Bouncyness and sharp curves, AIUI.

Also, are the 172s going to be like the 378s or the more 'conventional'
design like on other BR trains?

Definitely conventional carriages and conventional-ish seating,
although I'm assuming it'll be wide-aisle 2x2 like the SWT 455s.
Remember, the aim among all involved is for the 172s not to stay in
LO's hands for very long.
