    GNRi Brake Van

    When drilling holes for handrails, I always mark the exact location for the hole with a sharp point, like a needle, or the point of a compass. When 100% satisfied with the position of the hole, then make a indentation with the sharp point. This then acts as a pilot hole for the fine drill required for drilling the hole, and ensures it drills in the exact spot..

    Grounded Bodies

    I have not seen this van in the flesh, just close up pics taken off the Google image. However, the end framing is more akin to the NCC than the GNR. The images below show the differences quite clearly. The first image is a snip from the Google image, and clearly shows that the two centre vertical frames continue past the horizontal frame at the top. The centre picture shows an NCC van end, which has the same frame arrangement on the end. The third picture is of a standard GNR van end, which clearly shows the difference between NCC and GNR van end framing.

    Close up inspection of the external framing would suggest that it could be an NCC van, rather than a GNR van.

    Dutch gen van

    The train is comprised of Mk 2a & b coaches which, being ex BR, have a different electrical system to the Mk2d coaches of IE. Three Dutch Vans were converted from steam heat to electrical generators to run with the Mk 2a & b coaches. Presumably two Dutch Vans were required in the formation in the clip, due to the number of coaches.

    Operating Dapol Semaphore Signals

    I have never used the Dapol semaphore signals, but from what I have read, all that is required is a momentary power connection , or pulse, to operate the signal. The simplest way for operation is a push button. The first press of the button moves the signal one way, the next press moves it the other way, and so on. The Peco point switch provides two such pulses, one for each position of the lever. Unfortunately, as it stands, this is no use whatsoever for the Dapol signals. However, today I dissected a Peco point switch, to see how it operated, and discovered that if the two outer terminals are connected together and then to one wire from the signal, and the middle terminal is connected to the other wire, the Peco switch will provide one pulse to the signal each time the lever is moved. By an ingenious lever mechanism, the pulse only happens towards the end of the lever movement, so it is very unlikely that the signal will get out of sequence with the lever, as the lever has to be moved fully before the pulse is created..

    Track Cutting Razor Saw

    It is sometimes better to have a slightly wider gap than that left by a razor saw, particularly where the gap is used for isolation purposes. In hot weather the track can expand sufficiently for the gap to close and cause a short circuit, or continuity where it is not required. Last week's hot weather did exactly that on an automated layout in a museum I am involved with. A train on a certain track kept overshooting it's stopping point, and a second train would ram into the side of it, causing a derailment. Investigation into the control equipment did not reveal any fault, and it was purely by accident that the closed up rail joint was found. Once the joint was opened up again, all trains ran normally.

    UTA "Brown Van" from Provincial Wagons

    Whilst admiring Nelson’s excellent work on the brown van, I happened to notice that on one side the doors opened to the left, while on the other side the doors opened to the right. Having assumed for many years that all the doors opened to the left, and never having seen anything to the contrary, I decided to do some research. I looked at dozens of pictures of brown vans, and in none of them did any doors open to the right, which I thought was a bit strange. Surely all the pictures cannot be of the same side of so many different vans. There was, however, one exception to this, and that was the recently restored brown van at Whitehead, which has doors opening to the right, at least on one side. I then checked a drawing which I have, and lo, the drawing shows doors opening to the left on one side, and doors opening to the right on the other. Now we all know how inaccurate drawings can be, so could it be that in this case, since I have not found any pictures showing doors opening to the right, that the drawing is incorrect, and the restorers have restored the brown van at Whitehead as per the drawing, and Leslie’s brown van kit is based on the restored van. I am sure, and hopeful, that someone will come up with an answer to this.

    Little models for little money

    Judging by the contents of the sets, these would date from the early 1960s.

    Murphy Model 086-no cab lights working

    Just checked a servo on a baby GM. Plenty of room above the coupling pocket, but care would be required in routing the thread so that it does not foul the buffer beam. There is also room underneath the pocket, but the servo would be visible from the side, although a touch of black paint would help to hide it. Better on top I think.

    I would say that there is an error in the description for the 6 pack. The six pack would seem to be a multiple pack containing enough parts to fit out three locos (6 couplings). I would also suggest making the connection to the function output on the loco circuit board, rather than the decoder. Much less expensive if you make a mess of it. I still have a 2 pack left from the original installation, so I will have a look at the implications of installing one in a baby GM. The friend I did the work for moved away shortly after the installation in the 2-6-4T, and left me with a second loco to do. I had said I would not start the second installation until after he provided me with a suitable decoder, which he hasn't so far. That was nearly three years ago.

    Noel, having installed two of those setups, I can't see any reason for any wear or chaffing to occur. After all, there is next to no tension required to pull the coupling open, and certainly, on the installations I did, there was no contact with anything to cause wear or chaffing. In the extremely unlikely event of the thread breaking, it would be easy enough to replace it anyway. I would have no hesitation in using that system, if I was using Kadee couplings.

    I hadn't seen that type before. Below is a link showing the type I fitted. The servo can be fitted anywhere as long as it is 90 degrees to the coupler. It operates by pulling on a length of fine thread.

    A couple of years ago a friend asked me to fit DCC remote uncouplers for Kadee couplings to a BR 2-6-4T locomotive. I don't use Kadees myself, but once I had installed the necessary servos and carried out functional tests, I found it was brilliant. Being able to uncouple a locomotive from stock, anywhere on the layout, was fascinating. No magnets required. I tested the loco for hours, just to make sure it worked, you understand..

    I had the same problem a few years ago, getting paint of a suitable shade. Below is a link to my original question, and the results.
