This is a total waste of locomotive power. Why do they need to top and tail four or five coaches when there are perfectly adequate run around facilities at every single terminus these new services serve.
There are
no run round facilities in the terminal platforms at Edinburgh Waverley, Glasgow Queen Street, Aberdeen or Inverness. So that's every terminus they will serve, and at Glasgow Queen Street and Inverness that accounts for
all the platforms, and there is limited capacity in the through platforms at Edinburgh and Aberdeen.
HSTs offer the flexibility, efficiency, fast turnaround and, to an extent, redundancy of multiple unit operation combined with quiet passenger accommodation. Plus a single loco wouldn't provide the proposed journey time improvements on the Scotrail inter-city services.
125mph running isn't required an any these scotrail diagrams
No, but they will operate at up to 100mph, and be quicker off the mark than the existing Turbostars.
I also believe there are thousands of coaches rotting in the siding at March etc. They can easily be converted. There can't be a stock shortage when thousands of carriages are rotting away.
Thousands? Don't be silly. The whole of the GWR mark 3 fleet totals c.450 vehicles, and even discounting the Scotrail conversions, these are still in the process of going off lease and GWR will be retaining around 50 vehicles themselves. Plus as has clearly been proven by the glacial pace of conversion being undertaken by Wabtec, with major delays being faced by all three customers, they
cannot easily be converted.
I've seen top and tailed freights coming through hexham on a regular basis with two loco and one wagon in between. What a waste of power and locomotive rostering.
Off topic, but I assume that you're referring to the seasonal railhead treatment trains. These cover convoluted itinieraries often with many reversals where it is far more operationally convenient to top and tail the formations than to have to find a suitable loop, cross a single loco over and run it round on today's busy passenger railway. Plus I presume you'd probably have to configure the cab-mounted control equipment each time as well. The RHTTs essentially operate as fixed formation push-pull rakes. This has been the case for the best part of thirty years at least.
Running these hst in Scotland is a total waste of money when the same service can easily be provided with one locomotive.
And where would these locos be coming from at relatively short notice (Notwithstanding the current delays to the HST refurbishment programme)?
