So, I got a sharp knife and started to shave the glue off - and the man's lower leg fell off onto the floor! You will realise that small parts dropped from a significant height can bounce off quite a distance in any direction when dropped onto a wooden floor. So, I then spent the next 30 minutes on my hands and knees gently sweeping the floor of my shed and searching through the residue for the missing leg - NOTHING! Know the problem - spent too much time hunting for small bits that have pinged.... and not finding them ☹️ 1 Link to comment Share on other sites More sharing options...
TEAMYAKIMA Posted July 18, 2023 Author Share Posted July 18, 2023 (edited) Three weeks after the Keighley show and I'm still finding damage that needs repairing plus dealing with issues which we identified at the show. There are many such issues and they're all relatively minor, but in the absence of 'big news' I will mention one of them. One issue which ruined the use of the Faller roadway was the excess of infra-red light which caused havoc with our IRDOT's. Whilst I accept that operating in a greenhouse was a 'one-off' (trust me on that!) we did, in the past, have problems at some venues with infra-red pollution from hall lighting - the NEC comes to mind. Even then, for some reason, it only seemed to effect the IRDOT's controlling the level crossing (since replaced with reed switches) and the IRDOT's controlling the Faller seemed to evade such issues - but it's better to be safe than sorry! So, now we have infra-red shields, painted matt black inside so as not to reflect the IRDOT's infra-red beam back down into the sensor. This one will never win a design award, but it does the job! It does, of course, have to be removable for storage/transport and its positioning has to be quite exact and so hopefully this helps in that regard......

TEAMYAKIMA Posted July 18, 2023 Author Share Posted July 18, 2023 In other news, we now have a new diesel - for a layout originally conceived to display the 'last of steam' I seem to be collecting a load of diesels. However, there is an issue with this being an exhibition layout............. If this was my home layout, I might want 75% of the trains to be hauled by double-headed QJ's and the rest by green DF4B's, but to the casual viewer that would be somewhat boring - most trains would 'look the same' to many exhibition visitors. By trying to make each of the main-line trains look as unique as possible loses some authenticity, but (hopefully) gains some viewer interest Anyway, here is our latest recruit - in fact I've had it in a showcase for several years, but only yesterday did I get around to fitting it with a 21 pin decoder. It's basically a shunter and so I'll have to think about how we use it. 6 Link to comment Share on other sites More sharing options...

This would ensure correct positioning, and avoid them moving accidentally. (not sure your team would want screws inserted into their wooden legs though) 3 Link to comment Share on other sites More sharing options...

You've been having problems with the IRDOTs from the beginning. None of them have worked reliably in any aspect you've applied them to. - the level crossing barriers, Faller roadway. Maybe its time to look at an alternative solution for the Faller rather then taking the 'sticky plaster' approach and introducing a fix to the problem, that will introduce a host of new problems. 2 Link to comment Share on other sites More sharing options...

Hello Al I totally agree that the IRDOT's controlling the level crossing were a constant problem and I took steps some time ago to replace them with reed switches. But, TBH, I have never noticed any problems with the IRDOT's controlling the Faller roadway - except in the greenhouse at Keighley and when we set the layout up in my garden in 2021 in 32 degrees of sunshine. As far as I know there is no cheap, simple alternative to having IRDOT's control the Faller - I know there are hi-tech solutions, but I have no intention of going down that route for various reasons - cost, time, complexity etc. Let's see how things go at our next exhibition. In the past I was always concentrating on keeping the railway running and with the railway now running reliably, I can spend more time concentrating on less important issues like the Faller. 1 Link to comment Share on other sites More sharing options...

There has been issues with the Faller all the way along, but it's been so far down the priority list that none of us operators have spent much time looking at it. We've been too busy just keeping the trains moving to care what the Faller was doing. 'No cheap' solution. Maybe that's were your problem lies. You have a big exhibition layout, and you will spend the best part of a thousand pounds on a loco, but you're not spend more than pennies on the control systems to make them locos run...

Again, I agree with you and luckily, as the railway is now far more settled, I will be able to concentrate on any Faller issues at our next show - Taunton in October.

But the picture above seems to show the tube cut away... From the Heathcote Electronics website "The sensitivity can also be adjusted by allowing more or less infrared be emmitted. Heat shrink tubing covers the emitter and detector. Its purpose is to prevent the infrared going sideways from emitter to detector. If this is trimmed back more infrared will be emitted and the range increased. However be careful not to expose both emitter and detector as the infrared will then travel sideways making the detector think it is permantly detecting a train. If longer pieces are shrunk over the top the range will be reduced. Normally none of these measures are required and the units work satisfactorily as supplied." - http://www.heathcote-electronics.co.uk/how_infra_red_model_train_detection_works.html Edited July 18, 2023 by luke_stevens 1 Link to comment Share on other sites More sharing options...

RMweb Premium Ian Morgan Posted July 18, 2023 RMweb Premium Share Posted July 18, 2023 There is a Merg 'Pocket Money Kit' for a Laser Train Detector (kit 4822) that apparently copes with varying ambient light by sampling and using clever algorithms in its microcontroller. At less than £3.50 each, it could be worth experimenting with as a straight replacement for your IRDOTs. 2 Link to comment Share on other sites More sharing options...

If you order figures from somewhere like https://www.modelu3d.co.uk/ this is pretty much how they come. I'm actually surprised that the supports are as thick as they seem to be.

It was just that the ebay photo I saw had them cleaned up - looking again at the ebay listing there is a second photo showing the basic just-off-the-printer version - I should have known better! TBH, I have loads of Modelu 'special one-offs' on the layout, but I always had them sent off direct to their designated painter and so by the time they arrived with me all that cutting off had been done. 1 1 Link to comment Share on other sites More sharing options...

As I've said, to my knowledge there has never been any IRDOT issue on the Faller except on a couple of very unusual scenarios where 'outside' infra-red has confused the system and now that I have made 'covers' for both ends that should eliminate any possibility of recurrence.
