Tonight I caught the 17.06
PAD» -Bristol
TM▸ (via Bradford-on-Avon) which left 10 minutes late (due to 'late running incoming services' according to the TM) and which then came to a standstill at Westbourne Park for about 45 minutes blocking Line 2 (and I believe the 17.15 to Swansea behind it) due to some sort of problem with the rear power car.
Eventually the train returned to Paddington arriving in platform 2 at about 18.10. Next fast train to Twyford was the 18.18 to Oxford but it didn't leave until about 18.35 due to the late arrival of the Turbo set from the depot. After a slow trundle along the Down Relief as far as Southall, I eventually arrived at Twyford at 19.14 instead of 17.27.

Can I please ask anyone in the know three questions?
1. Why did the 17.06 leave 10 minutes late?
2. Why did it fail at Westbourne Park and why did the attempts at rectification take so long?
3. And why (to add insult to injury) was the stock for the 18.18 to Oxford late in arriving from the depot?
Thanks!
