Dapol working signals review

Recommended Posts

Just taken delivery of the bracket signal.  To note, for those planning to use DCC control, the Dapol DCC Servo Signal Controller 4A-001-001 will not apparently work with this version of the signal.  Instead, a Dapol DCC Servo Signal Controller 4A-001-002 is required.  This doesn't as yet appear to be available.  Has anyone heard when this might appear?

 

The -001 controller has outputs to the signal for both power (the red and black wires) and control (the two yellow wires) when used with the most recently supplied GWR square post lower quadrant signal.  Without DCC control, the two control wires were to be connected to a momentary push button switch or a sprung 'centre off' toggle switch or other such equivalent. 

 

I'm assuming that the -002 controller will have three control outputs per signal.  The supplied notes for switch control of the signal labels the three wires Proceed, Common and Stop. Either a Latching, single pole, double throw or Momentary, single pole, double throw switch is suggested with Common being linked to the switch common.



If it is of any help, I received a news email from Train-Tech, and I quote a part of it here: 

"We are pleased to announce today that we have been developing a decoder especially for these new Dapol Servo signals which both powers them safely with a stabilised supply and controls two single arm signals or one twin head signal. 
It’s called the SC4, designed and made in Britain and is now available from stock priced at £40. Available to buy at the Great British Model Railway Show at the Motor Heritage Museum this weekend or Warley in two weeks time, or online from our webshop  ... "

I pass this on purely as I am also interested in the Dapol bracket signals, although I am awaiting the BR upper quadrant types. I have no connection with Train-Tech, other than as a satisfied customer.

I'm looking at putting one of Dapols signals on my layout, and as it is a portable one, have thought about using a 9V battery to power it. How would I wire it up?  I assume I would need to wire in an on-off switch to the circuit so the battery wont be drained when the layout is not in use. Ideally I would like to use a toggle or lever switch - and if possible a set-up so that the position of the switch matched the signal??

There's a review on you tube now, there is an bouncing in the signal arm when it goes up, looks you can adjust that.

The demonstration is on a 9V battery and under the black box there is af fine tuning for 1b and 2b, so looks like this is for the bouncing.

If al signals come like this in future its amazing for this price. 

 

Hope this will help

Thanks, it was actually seeing that video that gave me the idea! You only get a quick glimpse of the wiring, and I was wondering if someone had a clearer explanation, including the sort of switch used.

The switch used is an impulse one, no permanent switch, otherwise the motordrive is burned up.

There are 2 switches supplied with the package and that all for a average price of 55,20 at shops.

If compared with the other signals from Dapol at a average of 26,00 a single one,  you get two signals on a bracket ,plus bouncing device and two switches, i say a very good price for it.

Hope in future more of this in SR and LMS types.

Thanks, but I was talking about the regular signals, not the new junction signal! Sorry if I wasnt clear.
