Re: Ramp metering for model train set

Ramp Metering is a system that allows one or several vehicles to enter a motorway from the slip road (Ramp = USA term for UK Slip road) via a set of traffic lights on the slip road, used in UK on high congestion sections of motorways and normally come into work in the peak periods when congestion i...

Re: Cobalt Point Motors

There are basically three types on Cobalt motors currently produce (some may not be in stock at the time of writing this?). Analogue users are offered the choice of Cobalt Classic Omega or the Cobalt ip Analogue. The main difference is their operating DC voltages. Both have two sets of electrically ...

Re: Led Lighting problem

Low current LEDs are readily available though most "Normal" ones work on around 10ma to 20ma. Have a look at:- https://www.reichelt.com/gb/en/led-3-mm-low-current-red-led-3mm-2ma-rt-p21626.html?PROVID=2788&wt_guka=54951038155_263550070769&PROVID=2788&gclid=CjwKCAiA8K7uBRBBEiwAC...

Re: Led Lighting problem

Brian, thanks for the comments on failing LEDs. My lamps are being powered by a Guagemaster WM4 DC 1.25A wall mounted supply as I noted in my original post.I think there should be enough amps to cover the 900mA I am using with a bit to spare. There is a resistor pre-fixed to the positive lead to re...

Re: Hornby DCC Point clips won't fit

I assume you are/were (as its nearly a year ago now!) trying to fit them to Hornby points and not some other make of point? IMO They are really a poor job anyway! By far the best method is to use "Dropper" wires soldered to the rails outer web where track is already laid or to the rails un...

Re: Gaugemaster combi controller

I have purchased a led strip light it has 2 wires red/black can I put a switch on it and still plug it into my combi controller. Really the best is to use a separate 12 volt DC source. The output of the Combi is AC at 16 volts , LEDs like DC, though they will work on AC but keep the voltage at the ...

Re: Led Lighting problem

LEDs normally only fail if they are subjected to reverse polarity or over rated voltage applied without a series resistance in circuit. I would suspect if the one LED lit momentarily then hasn't worked since its failed due to one of two reasons. 1) As above, it was connected in reverse or has had to...

Re: New Layout Electrical Help (please) DC Layout

Thanks Brian To be clear, by using the slide switch to manually change the point, I was planning (more hoping) that the same switch would switch which controller was in control of the section. By saying avoid switching, I meant by having a third switch ie one for each point and one to select which ...

Re: What would be in the ground floor of a signal box?

Very slack working by the regional or area signalling engineer who would be the first head to roll if an accident occurred and it was proved the signaller/operations staff had free access to the interlocking! Closely followed by the errant signallers head! The concept was that RKB221 padlocks and ke...

Re: New Layout Electrical Help (please) DC Layout

You say you do not want switching, which is the only way of feeding a change-over section on a DC layout. Whether manual switches or point operated switching its still needed for DC and point operated would perhaps be a bit more complex as you don't have point motors. Perhaps a simple learning sessi...

Re: What would be in the ground floor of a signal box?

As a former real railway signalling (S & T) engineer, keys to under box locking frame doors, lever locks and circuit controllers attached to the levers are never accessible by the signalman. It would give the signaller a "Get out of jail card" if they had a key. Under box access door k...

Re: New Layout Electrical Help (please) DC Layout

Hi IMO what you're after is nigh on impossible without some switching being involved. :o TBH the simplest way would be to go DCC and use something like a Select from Hornby to power the whole layout. A child of three or over will work a Select easily! Then no sections or IRJs are needed with DCC as ...
