Fitting Blue Star to the loco(s) will not be required as the Blue Star system on the DBSO and stock has been modified to work with the Green Circle system on the 47.
Although 47712 will naturally be the dedicated loco for this set, this should mean that any Green Circle fitted loco will be able to work in push-pull mode with the DBSO.
A tour is pencilled in early next year following main line testing which will commence shortly.
The primary difference is a 180 degree rotation of the cable if I read correctly.
So I imagine it was a very easy fix.
47s are perfectly capable of reaching well in excess of 100mph and not just the 47/7s which were authorised for this speed.
Whether authorised or not, when the 47/7s migrated south to T&C services and then the 'Mule' as well as on Parcels trains and hired in for IC / XC services, many drivers took advantage of the sign in the cab which read 'Max Speed 100mph' despite it not being officially sanctioned on any other routes than those approved in Scotland.
Oh I'm well aware of that, but officially the ceiling was 95mph.
Even the 47/7s were not 100mph locos, as was explained to me, rather they were specially authorised to operate at 100mph on the Edinburgh-Glasgow line with special maintenance. If the maintenance lapsed, the officially reverted to 95mph again.
I don't believe the cab desk sign, nor data panels were altered, just a red plate denoting the modification was applied to the can doors.
Did see a photo of same somewhere.
The field diverts were also modified for 100mph running.
As it is, I don't see authority for 100mph being granted, if it was even something considered.
but nice to see all these retro liveries on railtours now
