Re: Scaleforum 2019

The poor souls who man the desk have enough problems without me. But when I tried to collect my (preordered) badge it appeared to cause a minor panic behind the desk -- and a bit of a queue behind me. I really felt I shouldn't bother -- but then they found it. But evidently name badges were not par...

Re: Methods for Removable Loco Wheelsets.

Meanwhile the hobby moves on, I wonder also Brian, if Will Lichfield’s series on csb passed you by? That kind of comment is a bit self defeating - it is merely a different way, not necessarily better . And for a beginner, the complications of a CSB chassis is certainly a step to far. While I accept...

Re: Track cleaning

Interesting, looks like the guy may have invented graphene. I've never been convinced by the suggestion you would significantly damage your rails with an light abrasive cleaning method.

Re: REF: Rail wheel profile and "to do" list update

I think there is little doubt that sufficient weight is necessary to stop the leading wheel from climbing the rail on corners, This is the implication of Nadal's formula, not to mention the real world accident investigations that Julian is fond of quoting. None the less, to assume that just because ...

Re: Waisted bearings for Bedford sprung W irons?

... So far I’ve had no success in making such a large slot without damaging the casting; perhaps the outer face of the bearing could also be filed down a bit? Yes you can file off much of the bearing. Think about it,the waisted bearing should have exactly the same size hole on the inside as the sta...

Interested to know how much of a problem the slight slop is .... is it visible when the wagons are running on the track? I suppose a tad of slop it could be argued might be a good thing?

Re: Singles and suspension

I have all but ruled out CSBs, as a solitary driven axle doesn’t bode well with them... Why? I know that conventional wisdom on CSBs has suggested in the past that you need the centre of three axles slightly softer than the outer two to prevent porpoising (rocking around the centre axle) but experi...

Re: Arrangement of levers in a signal box (meandering into the Quintinshill disaster)

I recall one P4 layout, relatively recently (but can't recall the name), where Single Line Working was shown. I think that was the only time I've ever seen it done in model form.

Re: Problem Arising From My First Morgan GWR Underframe

Jeremy may well be right and you may have assembled something the wrong way round. However there is another possible explanation. As we have discuses else where (see below), the combined length of axle and pinpoint bearings can be a bit variable, so you should not be too surprised if this sort of th...

Re: rail/wheel profile - prototype has problems too

Consider the horizontal force needed to push a vehicle back into line if it hunts and the leading flanges strike a rail. Using F=ma, the mass decreases (clearly) as the cube of the scale factor and the required acceleration as ... the square of the scale factor? Because the acceleration needed is l...

Re: rail/wheel profile - prototype has problems too

An Easter Day debate revolves in my mind Will. I don't see how the scaling effect of physics favours us particularly. Even though we all know that toy model trains comer unrealistic fast? And that Andy's video clip demonstrates this can also be true for scale wheels? I would have thought that the e...

Re: rail/wheel profile - prototype has problems too

A few years ago, the American Passenger Transport Association were evaluating a proposal to adopt a different wheel profile for LRT trains, one with a greater flange-contact angle. The idea was to allow higher speeds on sharp curves. Makes me think that a less-prototypical profile might help our ov...
