Turning right onto a roundabout is a rather extreme form of poor lane keeping. 🤨

Signalling a new layout.
Grovenor replied to Lord Street's topic in Modelling Questions, Help and Tips
Exactly, no rotation needed, and a better plan, watering facilities can be provided on the loop if required for bankers. -
Yet the self same delays are imposed by the government supposedly to save costs. 😆

Having personally worked on M23 machines, they are actually bigger than the Machines made by Peco although mainly in height, the length will be very close. I suggest you recheck dimensions. Personally I use Servo drivers that come as MERG kits but I'm sure that sketches for Arduinos are available. Note how far it overhangs the two extended timbers. Good drawings here, albeit the older versions that I worked on. https://assets.new.siemens.com/siemens/assets/api/uuid:0c6bacc1-3c75-4f78-894b-feade4fc1c9a/brochure-m23am3a.pdf They used to be Westinghouse of course.

GWML Electification
Grovenor replied to Xerces Fobe2's topic in UK Prototype Discussions (not questions!)
So a rather silly attempt to save a bit on the OLE design. Penny wise pound foolish! -
Your dummy motor is significantly under scale size, the Peco one I used for the demo is correct size although not correctly located. A scale size motor will easily cover the servo horn. As for the batter, you have to create enough level are for the extended timbers that carry the motor, anf the servo goes under the motor so should not be an issue. And we are not talking big hole, the servo I used is 6mm wide x 20mm long. Using servos you need a servo driver and you can have a relay working with that for frog polarity switching.
-
Ditch the linear actuators and use micro servos driving direct from the servo horn, recess the servo into the top of the board and put your dummy point motor over it. This was a quick proof of concept, The dummy motor can easily be arranged not to move when doing a proper installation.

Chain routing for simple hoist / crane
Grovenor replied to BroadLeaves's topic in UK Prototype Questions
The problem being with the kit instruction writers not having understood what they have made. IMHO The large pulley will have teeth so that the loop does not slip, there are special designs for these teeth to fit with chains. The other chain will be secured to the small pulley (drum really) so it winds onto it when lifting. The drum has to be designed to take the amount of chain needed for the maximum lift, not a lot with these sort of cranes. The way the instructions suggest there is no possible way for the operator to raise the load. 🙂 Ps. There also needs to be another control to lock and release the pulleys. The ratio one does get rigged correctly, although with a triple reduction gear it will take a heavier load but be much slower. https://www.buffersmodelrailways.com/ratio-531-yard-crane-plastic-kit-oo-scale -
Coach Gangway outer doors - usage on BR(SR) diagrams
Grovenor replied to Right Away's topic in UK Prototype Questions
How can one fit adapters if there are none available? Are shields supposed to be fitted somewhere? -
Chain routing for simple hoist / crane
Grovenor replied to BroadLeaves's topic in UK Prototype Questions
The pictures are not clear, especially the Metcalfe one which has the chain on the large pulley falling off. There are two chains, a loop round the large pulley. The chain from the load is wound up onto the small pulley. The difference in diameters gives roughly a 3 to one advantage when pulling on the loop to raise the load. -
Update from Hornby with regard to Oxford Rail.
Grovenor replied to Black 5 Bear's topic in Oxford Rail
And all the info in the Companies House database confirms that it is a subsidiary of Hornby and that the only 3 directors are Hornby directors, independent it certainly is not. -
Help needed to understand shunting options
Grovenor replied to Longhaireddavid's topic in Layout topics
And no need for a local shunter living in the engine shed and getting in the way of parking the autocoach. The train engines can do all the shunting required. -
My Lenz, Zimo, ZTC, MERG, Digitrax, Soundtrax, NCE decoders set it by CV29, not 12 and you enable or disable DC, when it is enabled it works just as you describe, the decoder looks at the waveform to see if it is DCC or DC and reacts accordingly, just as you described. This should not be a surprise its discussed in just about every description of the DCC system. However the ability of the software to accurately select varies among brands and some combinations of DC controllers and decoders work badly, and some decoders suffer fromrunaways when encountering shorts or power interruptions on DCC, when this occurs then its advisable to disable DC if you don't need it.
-
Well most DCC decoders do exactly that. So the HM7000 could also if the program was so written. But since it has an alternate way of swithing via CV12 using the app, then that automatic feature is not needed.

2 Supplies - 1 Track - bypassing a current sensor
Grovenor replied to alibuchan's topic in Electrics (non-DCC)
Surely the incoming DCC is seperate from the Loconet as shown in the diagrams. Presumably your modular standard has a DCC connection board to board that will provide the feed if using someone elses command station. What you have shown as +ve and -ve, more commonly labelled as J and K (following Lenz). Incidentally, in your diagram it should be the +ve, red, connected to the common of the detector module, as you have it -ve, black, goes to both sides of the track when switched through the module. -
2 Supplies - 1 Track - bypassing a current sensor
Grovenor replied to alibuchan's topic in Electrics (non-DCC)
I don't see an LN6061 on the Yamork product list. Do you mean the YD6016LN ? Anyway I don't see any need for switching to bypass the detectors, the track current can still pass through the detectors when using a different system and the outputs are not being used. -

What makes you think Lyndon Davies has left? Companies House thinks he is in charge https://find-and-update.company-information.service.gov.uk/officers/bltr97sd42rZgL7za-ieUbkRsWI/appointments -
And look at the back of the report to see just how much of an increase the top two got for running at a loss.

Proposed new competitor for Eurostar
Grovenor replied to Foulounoux's topic in UK Prototype Discussions (not questions!)
Take out the down escalators and there will be plenty of room for said border people to stand around and harass people leaving straight off the platform ends, plenty of room for a couple of tables and an X-ray machine to deal with suspicious baggage, and even for an interview room and body scanner for those suspected of drug smuggling. -
The report is very big on the superb skills and abilities of the IPA staff. But the results of their efforts are dire, Surely deploying those skills should result in most projects showing green, else they are not adding value and might as well be disbanded.
