    If you are modelling Deutsche Bundesbahn in the 1950s but are short of German coaching stock, feel free to drop in a Mk1 BCK behind the Danish coach: 100261.jpg

     

    The consensus here (German) is that it is indeed a Mk1, but no conclusion has been reached as to the how and why.

    The linked (German) site has an update as of 01/04 which reads.....

    1. The September 1956 Railway Observer has a couple of paragraphs concerning "BR standard coach BCK W21164" which "has recently been to the Continent for trials concerning riding of vehicles". (Wagennummer und -Typ schon hier erwähnt.)

    2. Keith Parkin, Supplement to his BR Mark 1 Coaching Stock book, relating to the ride quality of BR1 bogies:Page 26 - “E S Cox informed the institute of Locomotive Engineers that, in new condition, this bogie produced an excellent ride; it astounded both its owners and continental administrations when it came out near the top in competition with the best European designs in a series of very carefully conducted riding trials in 1956-7 over French and German tracks under the auspices of O R E.”
    (Allerdings ganz erstaunlich: bei uns war der BR1-Drehgestell für schlechte Laufqualität berühmt!)

    As the springs are, I guess, very light in their springiness why not try this to make your own:

     

    Materials:

    Appropriate gauge copper wire

     

    Tools:

    Two sets of pliers

    Appropriate size drill bit

    Wire cutters

     

    Method:

    1. Cut a length of the wire.
    2. Stretch the wire with the two sets of pliers, this has the effect of both straightening the wire and slighltly work hardening it (making it slightly stiffer and thus slightly more 'springy').
    3. Hold the drill bit in a chuck (or vice) whilst at the same time clamping one end of the straightened wire to the shaft of the drill bit.
    4. Wind the wire around the shaft of the drill bit, keeping it under tension as you go.
    5. Remove the 'coil' from the drill bit shaft and elongate the coil ever so slightly.
    6. Cut to length and try it out.
    7.  Let us know how you get on.....

    Fair point, a balance somewhere in between then.

    Aye, keeping the accelerator pressed just enough to prevent too much retardation when going doan a long steep hill - simply lifting off will cause the motor to regen to its 'balance point' which can be as low as 4 mph.

     

    It's a fine art to keep the needle on zero if you really want to 'coast'.

    Wouldn't it make more sense if the KERS didn't kick in until the brake pedal was pressed? 

    Not to a Yorkshireman - saves pounds on brake pads 😁

    There are many different concepts with EVs, two extremes being with the aforesaid MG5 and the BMW i3.

     

    On the former, take your foot off the brake and the car moves (think conventional Auto Transmission) whilst on the latter the car stays still until you depress the accelerator.

     

    On a different note some EVs don't cut motor power when the (foot)brake is applied when stationary thus potentially leading to motor overheat events.

     

    That said, I do wonder why manufacturers bother fitting handbrakes to UK cars these days as it seems most drivers seem to sit with their foot on the brake, without giving a flying f*ck thought about the driver behind that is being dazzled. No doubt the clutch will be help depressed where the vehicle requires it too.

     

    Not a lot of car sympathy there then - ah, but wait, it doesn't nmatter cos it's probably leased.....

    Of course, the boot would be on the other foot if you braked sharply and your brakelights didn't come on...

     

    That used to be the case for SAIC Motor Roewe i5 (MG5 SWEV in the UK). In KERS level 3, brake lights didn't (used to) come on when you lifted off the accelaerator though the deceleration was pretty rapid.

     

    A software update soon followed 😆; the first rash of insurance claims - probably!

    I had the same problem and resorted to removing the bogies, completely, to access the frames/keeper plate from the top : Unplug the cables ( centre of end of circuit board - they'll put up a fight ) then unclip the cover at the top of the gear tower. The bogie will come away after a bit if wiggling ........ yes, reassembly is fiddly too !.

    Thanks for your prompt reply.

     

    In your earlier post you ere concerned about damage to the pcb plugs - i assumed they survived?

    Presumably the test rake of coaches was fitted with these (as eventually were the Mk2s used for E-G push-pulls).

    The drawback being that you couldn't just use any coach available, they had to be so fitted.

    A further drawback being the propagation delay along the Reg Air pipe controlling the throttle on the rear loco. Bet that made for some interesting "seat of the pants" driving experiences ?

    And the reason why D1938 was propelling at high speed was because it had been fitted with Blue-star control jumpers.

    IIRC it was also tested on Paddington-Birmingham runs.

    Is that true?

     

    Blue Star MW does (did?) not provide throttle control for locos operating in multiple, that being done by the white 'Reg(ulator) Air' pipe on the buffer beams of MW equipped locomotives.

    Was that the same for D6700, then? - it was used for the G-E tests. 

    D6700 was so fitted from new IIRC, whereas the Brush Type 4's weren't.

     

    As an aside, I discovered relatively recently that some of the early build 'Peaks' had blue star MW when new but had it removed quite early in their lives, presumbaly Type 4 power (Class 40s excepted) were deemed not to need MW provision.

    The Boot is a regular(ish) watering hole, although The Dragon (same group) in Willington is nearer to me.
