RMweb Gold JohnR Posted November 12, 2019 RMweb Gold Share Posted November 12, 2019 Thanks, but I was talking about the regular signals, not the new junction signal! Sorry if I wasnt clear. Link to post Share on other sites More sharing options...
norman Posted December 16, 2019 Share Posted December 16, 2019 Are the 00 single signals now operated by servo? The old ones on the club layout have all now failed and there does not appear to be a remedy save replacing them all with the same design. The new O gauge single signals seem far better especially because they can be switched from proceed to stop with a single pole double throw switch.

RMweb Gold Adrian Stevenson Posted December 16, 2019 RMweb Gold Share Posted December 16, 2019 Hi Norman, the OO gauge signals are also servo operated. Cheers, Ade. Link to post Share on other sites More sharing options...
norman Posted December 16, 2019 Share Posted December 16, 2019 Is that for the single and bracket signals? I wonder what happens if you send back a failed single signal to Hattons? Link to post Share on other sites More sharing options...
RMweb Gold PaulRhB Posted December 16, 2019 RMweb Gold Share Posted December 16, 2019 You’d be best asking them if still under warranty. After 3 months they may take them back through the shop or suggest a direct route to their repair agent. Link to post Share on other sites More sharing options...
norman Posted December 16, 2019 Share Posted December 16, 2019 I've just looked at both Rails and Hattons web sites and they both show the old design of single signals. Only the brackets are servo. Warranty is 12 months surely not 3 months. The shop is responsible not Dapol or its agent. Norman Link to post Share on other sites More sharing options...

Quote The control unit houses the servo motors and the PCB board and clips onto the base of the signal once you have installed the signal super structure. at this current time there are no plans to change over to this method of control for the single arm signals in OO or N Gauge but we may investigate the possibility in time.

norman Posted December 16, 2019 Share Posted December 16, 2019 Hi Freebie thanks for the info: "there are no plans to change over to this method of control for the single arm signals in OO" That's what I feared. The old design is a disaster and a good solution is available but ............ no action. How sad is that. Norman 1 Link to post Share on other sites More sharing options...
Waverley47708 Posted January 20, 2020 Share Posted January 20, 2020 (edited) I bought three Dapol signals recently, two home and one distant. The first one stopped working after less than 5 minutes! As a result I put them away for a while. I took the advice on RMWEB and bought a 12v DC smoothed and regulated transformer. I also bought a couple of Heathcote Electronics automatic controllers for them. 3 signals, a new transformer and the Heathcote units and we are well over £100. Sadly within 5 minutes of getting the two remaining signals out and connecting them to the new power supply, the second one went pop aswell despite using the recommended power supply after. Two down one to go. This has to be the worst model railway product I have ever had the misfortune of buying. I know what I'd vote for if the British Railway Modelling awards had a category for worst product of the year. My advice if you are contemplating buying them is simple - don't. Seems the best solution may be to convert them to servo control. Based on the failure rate I've experienced Dapol must have a skip or two full of them from returns. Maybe they could do us a favour and sell them at a knock down price so we can add servos and have a working signal that last more than 5 minutes.

Dapol recommend no more than 9v these days and I run mine on 7.5v without any issues at all. Mind you conversion to servo control sounds like a good plan especially as the new junction signals they have produced use servo control or so I am led to believe.

norman Posted January 21, 2020 Share Posted January 21, 2020 Dapol recommend 12 volt - according to the info sheet with the signal. A regulated supply and lower voltage may be of benefit but the recommendation from Dapol is 12 volt. At our club we have collectively bought more than 20 and only one or two are still working. all connected as per instruction sheet. I asked DCC supplies recently if they had any failed ones for sale because I thought if there were enough I could make a little business converting them to servo control. But they said they have no stock. I've seen them being sold cheaply at shows in the past but they must be just chucking all the ones returned.

RMweb Premium Richard E Posted January 21, 2020 RMweb Premium Share Posted January 21, 2020 I was under the impression, from what I had read elsewhere, that they had dropped the voltage considerably from first launch because of the reliability issues. I am unimpressed by the in built limit switches as well, they seem pretty hit and miss. Link to post Share on other sites More sharing options...

No my first mistake was buying them! I can confirm they recommend 12v DC. They say you can use a 9v DC battery, and pretty sure it still refers to 14v AC. As I say I even bought a 12v DC smoothed regulated transformer specifically for them and still 2 have failed. 1 Link to post Share on other sites More sharing options...

Yep, as per my earlier post I lost £70-worth of signals in the same way, but the worst thing was Dapol's refusal to accept liability, even after such a short time on the layout; they were very rude and dismissive. 1 Link to post Share on other sites More sharing options...

Buying a 12V regulated *transformer* seems an expensive way of doing things - a 12V regulator circuit can be built and wired into the output from an existing transformer for under £1!

RMweb Gold The Johnster Posted January 26, 2020 RMweb Gold Share Posted January 26, 2020 I was appalled by the overbrightness of the lamps using 12v DC, and bought a regulated DC power supply from the electronics stall in my local indoor market, with different voltage setting. Cost me £5.75 and I'm sure I could have found cheaper online if I could have been bothered. I'm running two signals off it, at 6.5v, and they work ok. I'd still like the lights to be a bit dimmer (a real oil lit signal lamp is not particularly bright) but this is the best compromise; lower voltages would not allow the arms to work. The problem isn't so much the light as shining through the red and green spectacle plate on the signal arm as the amount of white light spilling out of the side between the bulb and the spectacle. I am experimenting with methods of baffling this light, but am so far more baffled myself! I bought a left hand splitting bracket as soon as they came out, and this, as has already been noted, is a much better model. The light levels are more acceptable (but still spill a bit) and the operation seems much stronger, and seems to replicate the 'pull' of a signal being pulled off and the spring back and bounce when the lever is returned in the frame. The additional load of 2 extra arms proved too much for my original market-bought power supply even at 12v, and I am running them off a 9v DC supply whose original provenance is as one with the snows of yesteryear. 1 Link to post Share on other sites More sharing options...
Suzie Posted January 28, 2020 Share Posted January 28, 2020 You could dim the LED further by running the Dapol signal on something like 6V AC via inverse parallel diodes. Just add more diodes in one side to dim the lamp. It will take a bit of experimentation to get the appropriate brightness. The mechanism inside is regulated and rectified, but the LED is not. Alternatively if you don't mind taking the signal apart you could replace the internal 820R resistor with a higher value to suit. 1 1 Link to post Share on other sites More sharing options...
sigtech Posted February 16, 2020 Share Posted February 16, 2020 (edited) Hello Johnster, I now have a total of 7 working Dapol 00 lower quadrant signals fitted on my layout 'Sproston', two of them being on one of the new LH brackets. They are powered by a redundant 3 pin plug-in charger with an output of 5.8v DC. This feeds the seperate + and - under baseboard terminal strips, to which each signal is then wired. I treat all the lenses of the signal lamps with a thick coat of Tamiya x-24 acrylic 'clear yellow' paint, which reduces the brightness still further, and gives a gentle yellow tint to the light produced, simulating oil lamps. I will add a few photos of them on the layout. HTH. Regards SIGTECH. Steve.

TomD Posted March 29, 2020 Share Posted March 29, 2020 Just for the record, I have two of these n gauge signals, one of which is triggered by an approaching train, which runs on a shuttle automatically every five minutes or so. I've run it for more than a year now, so it's got hundreds of hours in, and has run without any problems whatsoever.

norman Posted March 29, 2020 Share Posted March 29, 2020 Yep - that sounds like a record for the Guiness book - possibly unique. On the other hand there are very many that fail very quickly. Norman Link to post Share on other sites More sharing options...
RMweb Gold papadelta Posted April 28, 2020 RMweb Gold Share Posted April 28, 2020 (edited) Hi I am considering purchasing a couple of Dapol GWR Bracket Signals (4L-001-005). I can't find any specifications on the web. Could someone please advise dimensions, in particular the servo box that sits below the base board. I am a bit tight for space. Cheers Edited April 28, 2020 by papadelta spelling Link to post Share on other sites More sharing options...
RMweb Gold The Johnster Posted April 28, 2020 RMweb Gold Share Posted April 28, 2020 (edited) Clearance below the baseboard depends on the thickness of the board, but you need a minimum of 64mm below the baseplate of the signal, inclusive of the thickness of the board. Length of the gubbins underneath box is 58mm and width 50mm, but don't forget you must allow about 5mm minimum extra clearance at one end for the wiring and connectors, and because the signal only mounts one way into the gubbins box (you physically can't mount it wrong and there is a yellow line to show you the correct alignment), you don't get a choice which end! Height is 148mm from baseboard level including the base plate, and width 48mmm across the signal boards themselves from spectacle plate to opposite signal board end. The gubbins underneath box is quite bulky if you are strapped space down there and the casing could be presumably cut away if this helps, but I don't recommend it as it will be a fiddly job as well as voiding the warranty. If you have to resort to this I'd suggest replacing the removed casing with plastic sheeting to keep the dust out; there are 'no user serviceable parts' in there. Ensure the gubbins box is sited somewhere it is safe from accidental knocks and bumps, especially important on a layout that is not permanently erected, and it may be advisable to build a protection box for it if you cannot do this; more space, which is your problem in the first place...
