Set 2 - A Conundrum



This is a quick posting , just to record that there's been a bit of progress with Set 2 since I last reported on it , but mainly in the hope of flushing out some info to resolve a problem that is delaying progress:


Here is the underframe of the Brake 3rd (the composite is identical) - I have played about with contrast on the image so you can see the framing . Posed on it is a Comet LMS battery box casting




Two problems are immediately apparent . Firstly, the battery box casting is just a little bit longer than the gap between the cross members . Secondly, there is a cross member down the middle of the coach.


The only photo I am aware of showing a MR suburban as converted to electric light ( in Historic Carriage Drawings 2: LMS) shows a vehicle with a centre mounted battery box, and a flat centre section to the trussing- an example of the sets produced for the London area, which differeed in this respect (and presumably therefore had a different layout of underframe cross members)


There's also the question of the large gas lamp pots on the roof . Were these removed on conversion to electric light?


I did ask the question in what seemed like the appropriate existing thread, here http://www.rmweb.co.uk/community/index.php?/topic/51824-ratio-mr-suburban-coaches/ but it didn't draw any response


Since then I've had another look at the various drawings in HCD 2 . Two things are obvious - battery boxes were always mounted to floor level , and LMS battery boxes are exactly the same size as LNWR ones. Both comprised two compartments for the batteries.


Except that on some 65' WCJS clerestory stock there are two half-length battery boxes and probably some 2pm Corridor stock shows a short battery box (at least the photos of the brakes do, though the drawing doesn't)


The only solution I can see at present involves sawing the Comet casting in half in a mitre box , and making good the missing side with 20 thou plasticard to produce 2 x single compartment battery boxes, one of which can be installed either side of the centre cross member. From first principles , this is the only way the LMS can have done it......


Is any one able to shed any (electric) light on this one? I can't make up the underframe till it's settled, and I can't do the roofs until I know if the centre lamp pots should be there or not.


In the meantime , the coaches have reached this point, with partitions, seats and weight installed in the brake.




For the composite, I have made up a partition with lead sandwiched between plasticard (these were essentially all firsts with additional partitioning to narrow the third class compartments)




I've also drifted into yet another project , which will be written up in due course - converting a Replica BG to an NRX container van using a Hurst Models etch I bought second hand years ago (The BG was an ill-thought out impulse purchase at Peterborough 2 years ago, so this is another nil cost /clear the cupboard project)


On the credit side, the Dapol LMS nongangway lavatory brake third is finished, except for a bit of weathering
