meatloaf Posted May 16, 2020 Share Posted May 16, 2020 Currently im using modified code 100 electrofrogs with the polarity being switched with dcc80 autofrogs. Im considering swapping to code 75 and at the same time using the newer bullhead points. These are unifrog. Ive used unofrogs before with the 0 scale set track points and one power feed fed power to the entire layout so all routes were live, but as it was a simple end to end I didn't do any additional wiring So with the bullhead points do I still need to modify them and can I still use the dcc 80 to switch poliarty?

Sol Posted May 16, 2020 Share Posted May 16, 2020 As far as I have read about the Unifrog, already modified & the frog can be left dead or wired to a device to switch it so I guess the DCC80 would do the trick. Link to post Share on other sites More sharing options...
John ks Posted May 17, 2020 Share Posted May 17, 2020 Out of the box Unifrog points need no modification There are bridges under the point to link all the RH rails(see yellow arrows) together & all the LH rails together (red arrows) There is a wire from the frog, green arrow indicates its end If left disconnected there is about 25mm of dead track at the frog Depending on what locos that you run through the point you may not need to power the frog With an unpowered frog 0-4-0 & other short wheelbase locos could stall The frog could be powered with a switch interlocked with the point blades or a frog juicer as Sol said 2 hours ago, Sol said: so I guess the DCC80 would do the trick.

RMweb Gold BoD Posted May 17, 2020 RMweb Gold Share Posted May 17, 2020 I decided to try them without wiring the frog but when I laid them I made sure that the wire from the frog passed through the baseboard in case I needed to make the frog live in future. I haven’t needed to do this but the wiring is still in place should it ever prove necessary. The shortest wheelbase I use is a class 08 0-6-0 shutter and it is fine with them. 1 Link to post Share on other sites More sharing options...
