Class 73, 73140 and CIG 1497, on an afternoon of push pull testing following a morning re-commissioning the brake and power systems whilst squeezing in between the Thomas event service trains..
I've had many a past experience of working push pull in the past. For the down trip I was explaining the various driving techniques whilst assuring I was up to speed myself on the latest speed restrictions. Return trip I was observing and carrying out an assessment on the driver in the seat.
