Hear you on the higher coil resistance.

Right now some of my signals are 151 semaphores and the others are 153 with traditional bulbs (my stuff is all post war conventional). Once I get things running, will look at upgrading to LED lighting for the O22s, 153's, probably everything. In the meanwhile, it has proven easier for me to get my simple mind around DPDTs...

Can I clarify on the capacitor -- I put it across the poles of the relay, whether or not I power it with a bridge rectifier or a DC power source? And the suggested resistor, what does small mean in terms of ohms?

And thanks for the capacitor math - I asked for it!
