    Hawkins Street is open from 1 to 5 pm on Sundays now.

    I worked in a switchgear factory that made some circuit breakers for Zimbabwe Railways - we had two chaps come to the factory to learn about them - the two biggest people that I've ever seen - Max Dhliwayo and Alex Makomva - each the size of a telephone box and without an ounce of fat on them - it would have been interesting to see somebody try to get them to sit in the 'blek' section... I've tried for many years to track them down, but I just can't find them.

    A spring washer under the thumb-screws helps - as the balls in the joints aren't very spherical. This helps to take up the slack a bit, if you move a joint to a 'loose bit'. The croc-clips are easily replaced by something better, if you find some. For a few quid, they're OK when you need them.

    Is that Bailey's in the squeeze bottle?

    It can help, up to a point - but extra weight is weight that you also have to drag up the slope - the beauty of the magnetic system is that you get extra download without the extra mass in the train as well..

    Basically, it increases the downforce from the loco to the track, without increasing its weight. Wheel-slip is the main mode of failure on a slope, rather than lack of power and this will raise the point at which slip occurs - allowing a steeper slope and/or longer trains... Back in the old days of steel track, there was the Magnaforce system, which had a similar, though much less significant, effect.

    A straight gradient can be a small touch steeper than a curved one - it's a matter of making the best use of the space you have in terms of the relationships of straight to curved sections. I got away with lifting two and a half inches on an eight-foot long straight gradient with a double-bend entry to it. Trains would noticeably pick up a bit as the last wagons/carriages came off the (flat) bend and onto the slope.

    Bit of chat recently - here - http://irishrailwaymodeller.com/showthread.php/2843-gradients?highlight=gradient ...

    I like the Pringles storage racking idea.

    Of course, flet roofs are what they have on some buildings in South Africa.

    I felt that one coming....

    That's it exactly - just don't 'connect' the track to the baseboard in a 'hard' manner.

    The cork sheet that I've seen is actually made from reconstituted cork - cork granules in a binder matrix - and is a good bit 'stiffer' than plain cork sheet would be.

    A search for 'Murphy models' often brings up pictures of the US model Carolyn Murphy - well, that's my excuse.

    Mmm, you can always let the tyres down a bit - http://www.bbc.co.uk/news/uk-northern-ireland-29963418 .....

    The bag exchange system was still in use in GB until 1971. I saw it done a few times in the mid-'6os - very violent - do not post antique crystal decanters by this method....

    The track ramps can 'nudge' the bottoms of Murphy bogies - not enough to derail them, but, you have to be careful.

    In action.

    That's the 'collect and drop' model. The cams to lay in the track can be a bit finnicky - and the bags are difficult to obtain, though you could make something suitable.

    The brushes and the commutator in the pancake motor aren't always the best - and can dig in a bit where the brushes run over the breaks between the copper segments. The flywheel-effect of the rotor at speed helps overcome this, but with low-speed running, it will often stall. A bit of rounding off of the copper edges can help. This problem gets worse as the carbon brushes get shorter.....

    Don't we get a free kick for off-side?

    There's surprisingly little news attention to this story - http://www.itv.com/news/update/2014-11-08/police-investigate-reckless-attempt-to-derail-a-train/ - seems to have been rather a near thing.....

    The staff figure on the platform is particularly excellent - what's the source?
  25. Broithe
    Indeed, and particularly useful for 12V 'grain of wheat' bulbs - I usually run them at around 8V - a nicer light and they last for ever - two in series off a 16V supply...
