This Model of the Week is bang up to date and represents the very latest in passenger provision on the FR: the Service Carriage.
This vehicle takes the railway back to the Victorian era of the curly roof luggage vans (and their non-curly cousins) as a bogie vehicle in front-line service which doesn't carry any passengers - apart from the one's sitting down to use the loo, of course.
The concept is a carriage which combines all the functions that would normally be dotted about the train in other vehicles such as the guard's compartment, a toilet and the kitchen / buffet area.
124 goes a stage further because it also holds a generator to provide the electrical power for the carriage's equipment.
124 is not an entirely new carriage. The bodyshell - which is rather ugly, if we're being honest about it - is brand spanking new but it has been plonked on a third hand underframe which was once upon a time a carriage on the Isle of Man Railway, then ran around as 1981-built 'tin carr' 121, before that was scrapped and re-born as 124.
It most respects this model of 124 was a fairly standard 'Barn' build with the exception of the glazing.
To give the crew some privacy some of the windows on the real carriage are covered in a reflective film, the kind that allows you to see out from inside but which looks like a mirror on the outside.
How, we wondered, were we going to recreate this in model form? The answer, in fact, was to do exactly the same as on the prototype. We were kindly given an off cut of the self-adhesive film used on the windows of 124 which was applied to the back of the styrene glazing, and it works a treat!
