Thank you Nigel, yes I did mean volts, no high speed, it's 40s era and I intend  running at scale speed and I guess with n gauge less of a of problem with the lower voltage.

Well I've found an old PSU, 15A  4.2A DC with the correct plug, is the 4.2A  going to be ok?

Thank you Andrew, there's plenty of choice, will check what i have in the loft first.

Richard

Thank you Nigel, very useful to know,so the PSU i've seen on ebay will be fine, only 2.5amp though.  I'm not planning on sound at the moment but probably  in the future, this is my first venture into DCC and my first "proper" layout. 

Richard

Thank you both very much, that was just what I was hoping to hear, especially the old IBM PSU, I might even have one knocking around,  time to visit the loft!!

By the way, my layout is N gauge.

I have just acquired a Digitrax Zehyr DCS50 but it does'nt have a power supply (DCS51) and these seem to be unavailable, could I use a laptop style switched 18v 2.5a dc pwr supply or  must I use a transformer type, I have read DC can be used up to 22v or 15v AC, anyhelp would be appreciated.
