LSL ScotRail push/pull set.

[12LDA28C]

I would imagine if this was being prepared for railtour duty that there would need to be a dedicated catering vehicle, any plans for that? In service a Mk.2D Micro-buffet was used on Aberdeen services, but I would think a mk3 catering vehicle would be used for future excursion use

Mk III Buffet vehicle 10404 is in ScotRail livery and will form part of the dedicated formation which will also include 2 x TSO, 2 X FO and DBSO 9707.

Just having a trolley would be more accurate, but I understand they have a TSOB in the set?

Green circle, blue star, orange square, TDM, 2 wire……

nothing like having a universal standard…..

There never really was one!

Or was that your point?

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.

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.

I believe 95 was the official maximum, speed but those at the top knew that it wouldn’t necessarily be stuck to.

With the slow demise of TDM, blue star and AAR are the closest you’ll get to a locomotive multiple working standard in Britain.

Those GBRf 50’s’ll still be able work in Multi with the Hanson Hall example?

Indeed - even if it were possible, it would be a fruitless exercise to fit TDM, given that it's being ripped out of Mk3s, Mk4s and (eventually) the Class 90s.

You can't rip it out of a mark 3 as uses lighting circuits, which use RCH jumpers, not sure about mark 4s but guessing it's similar.

That was the whole point of TDM - you could effectively use any coach provided it had the right heating and brakes (i.e. air brake and ETH fitted).

Mark 4s use separate jumper connections (UIC-spec or similar from memory); they don't have RCH jumper cables.

I meant the DVTs that were converted to AAR.

They could use the RCH jumpers on Mk3s (and earlier for that matter) but it has long been my indestanding that the WCML sets were fitted with screened UIC cables, as early TDM use in regular service found severe reliability problems partly caused by water ingress and partly by too much interference.

The much simpler 47/7 Brush system also suffered interference issues, but these were resolved by adjusting the frequencies/discrete timeslots - there was much less information to transmit with them.

So screened cables were used to resolve this.

I understand these issues influenced the decision to adopt screened cables as standard on the Mk4s.

Did the Mark 3 DVTs have it removed - I thought they retained TDM capability?
