As one of the new carriages is a powered vehicle it shouldn't make that much of a difference, as far as my non-technical assumptions are concerned: Seven powered carriages to propel a train of eleven compared to six powered carriages to propel a nine carriage train won't have changed the power to weight ratio considerably.I saw two today...northbound at say 12:15 and a southbound at 12:50 at Milton Crossing near Blisworth.
I'm sure they sound different to the 9 car units, maybe the engines are straining more?
They are given temporary numbers for transit and then when insetred in to a 9 car pendolino they are given the numbers that match the set.Are the new coaches being delivered without numbers and then being given numbers according to which set they get added to?
It all seems rather random as to which sets are being lengthened.
Assuming you mean the 1633? (1P21)The 1623MF Euston - Preston has been an 11 coach last 3 times I've travelled on it in the past two weeks, as has the 0840 and 1540 Euston - Manchester.
Do the 11 coach ones have regular diagrams, or am I just getting lucky ?
You may be looking at the new coaches/brand new sets. They are much shinier given they haven't had a number of years of being pelted by flies and any other rubbish the railway/local "youths" can throw at it!I've noticed that the 11 car sets look cleaner - particularly on the red area of the roof edge above the windows. Has there been a change in paint colour, or more attention through the washer?
