TPE compensated based on Bolton - Glasgow being declassified, as it was only that leg that was declassified and not the other leg.When TPE compensated your friend for the declass first class, was that compensation based on the cost of BOTH upgrades, or just the cost of the Ashton - Glasgow upgrade?
The upgrade only applies to Bolton as Northern doesn't have 1stThe one fly in the ointment is that if as you say the upgrade was for Glasgow - Ashton, and TPE are only providing DR for Glasgow - Bolton, how much of the upgrade cost should be included in the DR calculation?
I think pushing back purely to get this clarified is worthwhile but I'm not sure it's an amount worth fighting for.
