Advice sought on relays and associated electronic circuitry .

Hi , as a novice on electronics I need some advice as to whether a project started by my late father which I am trying to complete is viable as per the attached amateurish circuit diagram ( my one and not the Lenz one lol ) .I should explain that I am trying to operate 2 Seep N gauge electromagnetic uncouplers via 2 outputs of a Lenz LS150 accessory decoder and using 2 IN 4001 diodes as per the Lenz instructions to produce a 2 wire output as used for stall motor type points machines , the LS150 outputs approx 15 volts AC from it's initial 16 volts AC supply or rather I think it's an AC output but am not sure if the diodes rectify the current to DC ? ,I want to use the 2 LS150 outputs to trigger 2 non latching relays ( advice sought on type) to provide 18 volts DC to the 2 uncouplers from a seperate and dedicated 18 volt DC PSU , if the LS 150 is still outputting AC rather than DC with diodes in place ? I have a block signalling PSU1 device which can convert the AC to DC and offer 3 12 volt DC outputs to send the signal voltage to the relays , I hope this makes sense as my use of terminology is most likely incorrect ?.

Also remember to change the timing on the LS150 outputs or it will only operate the relay/uncoupler
for half a second.
