RMweb Premium Horsehay Railway Modeller Posted February 6, 2021 Author RMweb Premium Share Posted February 6, 2021 I have the signals plonked on the layout. Hoping to get them installed in the next few days and then I can touch up ballast etc. The junction bracket is causing a little bit of a fuss on the signalling thread as it is after the point, however if it was any closer to the tunnel it wouldn't be seen from inside. I think I shall install it there as is. I'm working on the assumption there is a repeater either in the tunnel or at the other end. I've read another thread on here with a similar issue and it seemed there were several examples of similar setups. 2 Link to post Share on other sites More sharing options...
RMweb Gold TheSignalEngineer Posted February 7, 2021 RMweb Gold Share Posted February 7, 2021 If I proposed putting a signal where you have it shown the Inspection Officer would be questioning what I had been smoking. When there isn't room to put a signal between the tunnel and the points there isn't going to be one, it will be in or on approach to the tunnel. If it isn't possible to see the signal then a banner repeater would be placed inside the tunnel or on the approach side to it. I can think of cases in real life where the points are close to the tunnel mouth and the signal is inside the tunnel although it would not be a full arm semaphore in that instance. In the case of points where the Facing Point Lock is mechanically held by a locking bar the signal would be about 60 feet from the points. If the FPL is held by a track circuit then the closest the signal could be is by the rail joint at the toe of the points although it would be most likely at least six feet further back and preferably 120 feet. 4 Link to post Share on other sites More sharing options...

To bounce or not to bounce... That is the question. I'm currently programing an arduino to run the signals. At the moment I've got the movement similar to other servo controllers. With a pull on, a little overshoot at the bottom and then a slight bounce at the top. I know if the signals were maintained and operated correctly there should be no bounce however I like the character it adds. The bounce and overshoot are based on a random number generator so they should be random every throw. All comments welcome 4 Link to post Share on other sites More sharing options...

Signals don't have to be tall. This one which used to be at Langley Green Middle had a station canopy and footbridge obscuring the approach when it was first put in. The reason why the right hand doll is tall is that there used to be a lower distant arm for the East box. In the case of your signal if you must use it I would make two alterations. Firstly shorten the arm reading to the incline and secondly cut the main post off just below the angled strut in the same way as the picture above. Position the signal by the joint at the toe of the points with the right hand end of the bracket 6mm clear of the side throw of your longest wheelbase bogie vehicle, which would be the Hawksworth coach in the picture of the branch train you posted. 4 Link to post Share on other sites More sharing options...
RMweb Premium Horsehay Railway Modeller Posted February 7, 2021 Author RMweb Premium Share Posted February 7, 2021 Just finished the hardware for the signal controls. Arduino uno, dcdc converter for servo power, Header pin outputs for servos and Inputs for switches. I'm just going for a row of switches so I can manually set signals. No interlocking or anything with points. I shall just pretend the correct interlocking is there when I operate. 3 Link to post Share on other sites More sharing options...
RMweb Premium Horsehay Railway Modeller Posted February 7, 2021 Author RMweb Premium Share Posted February 7, 2021 I've trimmed the post, it will be shorter when it's in the ground so to speak. The main arm is quite easily sighted from inside the tunnel. The junction arm is obscured until quite late. Is this OK if there is a repeater before it. 3 Link to post Share on other sites More sharing options...

I remember having one like that at the exit from a tunnel but it still has to go clear of the points, so you may have difficulties in sighting the main arm grom in the tunnel or the incline arm when close up with a train passing on the other line. The picture of it on the left looks quite good. The important thing is to see the main arm, but if slowing a train there is a problem then a repeater could be used. 1 Link to post Share on other sites More sharing options...
RMweb Premium Horsehay Railway Modeller Posted February 7, 2021 Author RMweb Premium Share Posted February 7, 2021 I think I shall leave it on the opposite bank as it looks quite good. I've just checked and its visible above a coach and can be seen all the way from the other end of the tunnel which goes 90 degrees onto the storage board. 4 Link to post Share on other sites More sharing options...
Railpassion Posted February 8, 2021 Share Posted February 8, 2021 Great to see your progress, very impressive in such a short time. Bravo. You could always use the bracket signal in the other direction to indicate a loop beyond the tunnel. 1 Link to post Share on other sites More sharing options...
RMweb Premium Horsehay Railway Modeller Posted February 8, 2021 Author RMweb Premium Share Posted February 8, 2021 I've started on the trap points. I've soldered some bent and filled rail to make dummy single Tonge traps on the two sets of sidings. Also the gang have been hacking away at the embankment to make way for a sand drag and retaining wall at the bottom of the Incline. 4 Link to post Share on other sites More sharing options...
RMweb Premium Horsehay Railway Modeller Posted February 9, 2021 Author RMweb Premium Share Posted February 9, 2021 Two lovely parcels delivered today. The corridor third I ordered arrived. Also as we can't go anywhere my gf and I decided on small early gifts for valentines. To my supprise She bought me a Bedford ambulance, a lotus elan, a vauxhaul Victor and some livestock. The lotus is a tiny bit new but I have plans to have it poking out from under a tarp in a garage so you shouldn't be able to tell exactly which version of the elan it is. I'm really happy with the corridor third, I've fitted kadees and now im just waiting for the brake, which is in the post. 4 Link to post Share on other sites More sharing options...
MrWolf Posted February 9, 2021 Share Posted February 9, 2021 Useless fact number 2077351(B) If the lotus Elan is the early model, the rear lights are exactly the same items as used on the FB Victor you have. 1 Link to post Share on other sites More sharing options...
RMweb Premium Horsehay Railway Modeller Posted February 10, 2021 Author RMweb Premium Share Posted February 10, 2021 The first signal is I stalled and operational. I just need to touch up the paint and bury the base in ballast. I'm also considering altering the code so it moves slower. Hopefully a video to follow. 3 Link to post Share on other sites More sharing options...
RMweb Premium Horsehay Railway Modeller Posted February 10, 2021 Author RMweb Premium Share Posted February 10, 2021 (edited) Here is a quick video of the first signal moving. Iv'e just noticed it doesnt quite move all of the way to the clear position, but this is easily rectified in code.

Railpassion Posted February 11, 2021 Share Posted February 11, 2021 Very nice. I'm a little concerned about the number of weeds on the engine siding. BR generally kept working lines shipshape.
