Re: Eames 40 flux

I am by no means certain here Steve, but I seem to recall that the "40" refers to 40% phosphoric acid, People might foam at the mouth at such a high percentage, but phosphoric acid is a very weak acid (it is a food stuff after all). Its low level of water explains its low corrosive effect ...

Re: Turnout construction - Question here please. Temporarily diverted into joggled turnout switches.

I take your point haha Howard but have to say the joggles on the layout this is intended for do not give any trouble in the trailing direction. I was actually talking about the real thing - LUL has a prohibition on joggled switches which are trailed though it uses them for "A" switches us...

Re: Singles and suspension

Not done one myself, but faced with the design challenge, I would be tempted to look at driving all three tender axles via spur gears using an adapted diesel loco mechanism - there are planty of them out there. The biggest challenge would be hiding it from view within a pretty sparse tender underfra...

Re: Arrangement of levers in a signal box (calling at the Quintinshill disaster, use of collars and setting back)

Provocative, moi? Many thanks for clarifying the "Green Book" situation for 1960 Jim. It is a bit of an irony that we all castigate the WR for marching out of step, yet in truth it was the Southern that was most different in signalling matters - mainy because they were a very different ra...

Re: Turnout construction - Question here please.

Just to mention that joggles can be a nuisance. Although they can help keep facing movements on the rails, they are equally likely to cause trailing movements to derail - Especially if they are a tiny bit overscale (which they always are!). So if your points are facing only then fine but If they are...

Re: Arrangement of levers in a signal box (calling at the Quintinshill disaster, use of collars and setting back)

Just to go back for a moment to the question of when the RCH Regulations began to apply, I was brought up on the Green Book dated 1st October 1960 (you can tell I have it in front of me as I write, and it is full of stuck-in amendments). Can I just ask what the publication number is of your edition...

Well, we can always send the boys round to make sure he do...

Re: Arrangement of levers in a signal box

The design of the lever frame, block instruments and reminder appliances may differ, but their application in accordance with the Rules & Regulations would not have differed by the British Railways era. Well, that is a sweeping statement if ever there was one and, off hand, I can't think of mor...

Re: Arrangement of levers in a signal box

I was sure we were in agreement! Of course, it is hard to know where the buck should stop in these things - I know that on the Southern, in very busy areas with either "Closed Block" or Sykes L&B, there was a very common slack method which, basically, avoided sending any bell signals a...

Re: Arrangement of levers in a signal box

The Hawes Junction accident of 1910 showed what could happen; the MR at the time didn't use collars, and there were no track circuits. Spot on - and the Caledonian failed to learn the lesson from that episode and were still not using collars in 1915 - even though they regularly shunted trains onto ...

What sort of box are we talking about Jim? Something large? Or small? A junction? A terminus? Speaking in the broadest terms, there are two basic ways of doing the job. One is to have all the running signals in centre of the frame under the block instruments, with points and ground signals spread &q...
