Double heading. The simplest way is as described earlier, to have both receivers bound to the same selection on the Tx, but that means that both locos do the same thing at the same time, if they are both powered. If already coupled together, no problem, they will drive as one unit. Or, with one loco...

Quick answers. A Tx22 can control as many receivers as have been bound to it, each responding to being selected when they are active/powered. Any number of Rxs can be bound to a specific selection, but only those that are powered will respond. So Nick is correct in that you could have as many sets o...

Mea culpa! I know I shouldn't rely on my memory, but sometimes I forget... The drawbar pull theory was that it takes about 2g per carriage to keep it rolling, and a little more, perhaps 2.5g, to lift one from rest. So JackBlack's 45xx should be good to lift 20 carriages or more on the straight and l...

The simple start is working on an assumption that most, if not all of us, have some sort of 12 volt DC supply, or an AC supply for DCC, available. A DC controller isn't required, just the power supply, an old-fashioned transformer with a rectifier, or a switched-mode 'wall wart' will do. On the test...

Forget batteries for now, the idea is just to see if radio control is a viable option. Our locos already have pickups and generally, 12 volt motors. So I wanted to try to fit radio control to one to see how difficult it would be, and if it would be worth the effort. My Bachmann diesels have very rel...

I don't think the camera was being false, on the contrary. One of the great dangers of model photography in this digital age is the light source. I reckon one was taken in tungsten light, and the other in blue sky daylight.

Starting with radio... Forget batteries for now, though the elimination of the dreaded pickup hiccup is the ultimate goal, controlling the first loco by radio does not require a huge commitment. The Tx22 transmitter kit is £38.00 and an Rx61-22 receiver £32.00. For those not comfortable with solderi...

Members and guests, Nick and I were very pleased with the positive responses to our demo table at this year's show. The number certainly exceeded my expectations! For some years in my past employment, part of my job was as training instructor on our products, and I never ran a course without learnin...

Will and Dave should call their 2-8-0s 'Bumble Bees'... some blinkered theorists say that they can't fly!

Dave Bradwell wrote: I just questioned whether the design was optimum. Ahhh, optimum for what? Current collection, weight distribution, haulage, ease of assembly/adjustment, or something else? Perhaps it just needs another csb for the pickups to get the downward pressures all the same - or simple c...

I can confirm that P87 wheels work fine with S4 track, and therefore probably with P4. I have been using wheels from the now defunct 'Railflyer' source, which look very similar, for some time. The insulating bushes came for 2mm or 1mm axles, and I have used both. Their 40" diameter wheel in P87...

Full springing of all stock really helps; battery powered traction solves the problem.

It would appear that my reasons for going to springy beams on the Finney 8-wheel tender have not been understood by some; Keith is right, the idea has been available to interested modellers for some time. In fact, one of my first P4 locos, an S&D 7F, had this feature and that was just after I jo...

Indeed Guy, and I have an untried idea for neggy rail pickups - a brass drawing pin. The dome shape should work smoothly on ramps, and it can be larger than proto to make sure it stays on the rail as it won't be visible. The pin part could ride in a piece of brass tube with the conductor wire fitted...

The Lanarkshire tender chassis has a slightly different axle spacing; between 1st and 2nd and 3rd and 4th are the same as the A3/4 tenders, but the 2nd - 3rd spacing is 1mm less on the WD tender. Get-away-with-able... The Brassmasters Easi-chas conversion looks like a better bet if you don't want to...

One other thought: would it be worth actually electrifying the conductor rails and picking up from those? Guy, I have tried this with some success... but. The main problem is getting the pickup shoes to behave. On most of the real things, the shoe beams are attached at each end to the wheel bearing...

Not for the faint-hearted, but a pencil can be used for very fine work. 2B or preferably higher. I take about 6-10mm of the wood off the non-pointy end, and wrap the 'lead' - which isn't of course, it's a mixture of graphite and clay, the higher the B the less clay - with foil, and clip over that. T...

We call ourselves scale modellers, right? A bit of the dreaded mathematics:- The real b-b according to the drawings from North British in one of my O.S.Nock books is 4' 5 and 5/8". Or 53.625" for easier calculation. Multiply by 25.4 (Millimeters per inch) equals 1362.075mm. Divide by our s...

I don't think there is any problem with our understanding of the basis physics, it just that there are always a lots of other factors which can have an influence on the final result as well.

Zebedeesknees I was not trying to persuade anyone to any particular method.
