The British Rail Class 121 is a single-car double-ended diesel multiple unit. 16 driving motor vehicles were built from 1960, numbered 55020–55035. These were supplemented by ten single-ended trailer vehicles, numbered 56280–56289. They have a top speed of 70 mph, with slam-doors, and vacuum brakes. [CAB] [INTERIOR] Scenarios: Lightwork: drive a Class 121 bubble car from Penzance To St Ives Mainline Diversion: Drive A Diverted All-stops Service From Penzance To St Austell Cruising The Bay: Drive a Service from St Erth To St Ives and Back again Mechanical Veteran: drive an all stops service from Penzance To Truro Platform 1 where it will go on the Falmouth Branch for the day Unusual Formation: A Class 150s engine has failed at Penzance, come out of the sidings at Long Rock and couple up to the Faulty 150 and continue its service to St Austell [HELPFUL LINK]
Great suggestion except that these were Class 122 units. The usual way to know is the Class 121 had a box for the 4 digit route indicator whereas the 122 had the smaller destination roller blinds. Otherwise they were remarkably similar. I am not sure that your Unusual Formation scenario would be possible as the Class 122 does not have the equipment to couple to a Class 150/2.
I rather see a Class 153 for this particular route, which would be beneficial if able to work in multiple with a Class 150. But any more first gen DMUs are welcome, especially the suburban types with doors at every group of seating.
I'd love to see the 121 on a branch line of say Didcot - Oxford in BR Blue on the GWE. That would mean extending the GWE from Reading but it is very close and I wouldn't mind them doing it, LOL. I know it will never happen but the real 121 is iconic to some. I would have it on any UK route it was seen on as well.
Really excellent idea but will not work since Class 121 is a mechanical diesel multiple-unit while class 150 is a Sprinter. Multiple units that the Sprinter class 150 supposed to couple with are class 15x Sprinters 17x Turbostar 14x Pacers all use a BSI Coupler.
You will probably know better than me but I thought most Loco's had emergency couplers that could connect to different trains no?
Yeah sure, although I'd prefer Didcot - Oxford but that will never happen. But saying that I'd still buy it for any route in England/Wales as I like the 121. Even as a Loco and then added to a route DTG could take my money, if they made a decent job of it of course.
My identification method was of more use in the years before the units received their full TOPS numbers. Before this they only had the shorter identification numbers which did not identify which class they belong to. The example in the photo at top of the thread is from the final years before withdrawal.
They actually need a converter coupler look at class 66 having an AAR Coupler with Buffer and Chains in TSW2. M7 M3 LIRR DLC there's a coupler adapter for those trains if You need MP15 locomotive to be coupled to them. What it looks like
