Re: LMS Super D question

Being big enough for the number was "anorak logic". It amazes me the number of spotters who hung around Bescot junction of an evening, in the 50s. Apart from the resident allocation of Super Ds and gronks the interesting stuff all came through mid day, it is in the middle of the country af...

Re: LMS Super D question

That makes sense, the cab certainly lacked depth, other locos could fit similar numbers on the side sheet so anything mounted on the side of the firebox would have been within the cab. I've seen cabs with wedge shaped boxes in a similar position, to allow the longest fire irons to be pulled complete...

LMS Super D question

A question I've never pursued,what was behind the box like extension in front of the cab alongside the firebox? One suggestion, in the days when they were all that could be seen at Bescot, was that without it there was nowhere big enough to apply the number!

Re: Triang/Hornby Vintage R.152 Diesel Shunter

That was my thinking in relation to the ends of the V spring. With that design of motor the whole frame is connected to the uninsulated wheels. There is one possible unseen source of a short circuit. If there is a motor winding to shaft short circuit you need to specifically test for it. With the or...

Re: Triang/Hornby Vintage R.152 Diesel Shunter

One vital point is to ensure that both arms of the V shaped spring are insulated, particularly the very ends, also make sure that the wire soldered to the tag that goes behind the brush spring doesn't touch the motor end plate.

Re: NEM box the downside.

I keep both lengths of Bachmann couplings, sometimes it's easier to mount it that bit further back, or you get a model with much longer buffer shanks. You should see the mounting for the Ratio diamond frame bogies mounted inboard of the balcony steps.

Re: NEM box the downside.

This was fitted with a very compressed version of the wedge shaped block with a hole through it that fitted over a peg. They centring action is provided by two springy bits of plastic, or in the case of the right hand coupler one, the other was hanging by a thread of plastic. Vertical adjustment was...

Re: NEM box the downside.

Then of course there's the introduction of "coupler droop", an ailment almost unknown in pre NEM days :roll:
but the continental manufacturers can do it right -------

Re: Hi from Australia

The only thing they got right about UK TT was the scale 1:100. Such an obvious choice, It now has its own band of supporters using 14.2mm gauge track.

Re: NEM box the downside.

@Bigmet, very similar to my solution to the gap. On some models the whole darned thing can be moved inboard by a couple of millimetres if it doesn't foul the axle.

Re: LNER is back

Try to fine them they'd point out the bits of the contract NR have failed to deliver/,complete on time and the arguments would go on indefinitely. The bidding process was like the West Coast one chaotic and unfit for purpose. Privatisation has been a total failure in terms of its purpose ( to save t...

NEM box the downside.

Compare these Mainline wagons from 1980 with today's offering from Hornby . The gap between buffers on the 1980 stuff is a bit over length, the sort of thing we put up with for having tight radius curves. By comparison the present day models from the major manufacturers have a ridiculously long gap....

Re: First time with point motors query

Ah! There's a problem with Hornby switches and CDUs. The Hornby switch fires both coils in sequence each time it's moved, so your CDU get partially discharged ineffectively firing the coil from the previous move first. The smaller Peco switches avoid this problem by a bit of clever mechanical design...

Re: Traing R.344 track cleaning car. Any good?

The original 10.5mm Triang wheel was their standard (even on coaching stock. This is why their standard buffer height is 1mm too tall. The later plastic bigie frames and chassis perpetrated the anomaly, short of putting in present day 10.5mm wheels it's a SOAB to correct. Does Peter's Spares do repl...
