Hail All!
On the subject of the impending DMU reshuffle, I and a friend were on a footbridge over the South West main line east of Farnborough earlier today and amongst other things saw a few 159s go past. One of them was around about the time in the table listed above by Sprog, so you never know...If the movement of 159102 was today, then me and my friend saw it and didn't even realise the epic journey that it was coming toward the end of! 8)
(Obviously I'm asuming that the SWT livery would have been applied at Doncaster works before transit!
)
On the subject of the 170s...I saw one of those doubled-up with a 159 go past at about 14:45 heading for London, so we do still have a few of those about as well...For now.
Farewell...
>> Death <<
P.S: If you're really cold, try standing on a footbridge just before a Class 66 goes beneath you...I did that earlier on today, and the exhaust fumes almost lifted me off my feet, as well as warming me up nice and crispy!
