    Prototype HST Power Car to return to the main line?

    in UK Prototype Discussions (not questions!)

    Posted

    The real trouble I can see is the amount of modifications made to the power cars from Production, to working 253/254 to modern mtu mile munchers...

     

    relay and control gear has changed spec from the valentas, twps/aws/otmr/atp have all been retro added between leaving the factory and entering service... thats before the three wsp systems, 36 way jumpers, sdl/cdl, buffet refits, lighting physical and electrical changes, inergen fire bottles, mtu engine and M-dec ( a HUGE computer box), shut down timers, guards windows blanked off in the van, exhaust baffle, oh, and then the cab console is all changed on fgw, if not other tocs. The mk3's are wired/orientated differently to conventional mk3's (modified ones have caused problems when incorrectly shunted), air pipes are being exchanged for neoprene hoses due to reliability issues, aside from buffers/couplers/power supplies.

     

    Problems I can forsee? the mtu's have a 110v starter motor and a weedy starter gear ring, the motors cost a small fortune to aquire, the rest of the world using mtu engines use cheap bosch 24v motors, the mtu engines are sensitive to poor maintainance, hence the turbo issues in the past and present fuelling issues caused by a lack of filters in the country...oh and the traction motors are starting to show thier age, god knows how much new motors, or at least comms, brushes, boxes and springs would cost - once all the motors have flashed over or shorted it's two days work to recommission and test a powercar - or if you catch it early you can lock out power notches and save the windings.

     

    Ultimately it would be best to preserve two mtu power cars and keep a set that fits with them. This at least means you could operate with trained drivers, within normal scheduling and on routes that timing can accurately be kept. Oh, and we would have a fighting chance of keeping the things running.

     

    Excue me for the brief details, I'm back off to clean up a set of traction motors... on a power car.

    I wondered if the nanny filter would blank it out.

     

     

     

    Does that apply to most depots or just some? And how come depots can handle the length of a 66 for example, but not a bogie tank? Would the discharge facilities need rearrangement for bogie tanks?

    (and who is "we" by the way?!)

    tanks in advance.

     

    us is st phillips marsh. On depot although long vehicles get moved around, the tanks get bunged down whatever road is free ( and that's not much late at night) It's not through lack of clearance - just practicality

    Its looking great lads, aas someone who works at a hst depot, nothing looks out of place or contrived (tho I'm personally not keen on the soft scottish decking between roads ;P)

     

    Have you tried putting a shore socket onto a mk3... I wouldnt think It was possible from the coach... but the handles would make it easier to plug it in, the plugs are big ally castings (apprentice test #34 - plugging in the shore with one hand)
