I'm scratch building the 181st bridge (that runs between the boogie down Bronx and Washington Heights, Manhattan) for my cityscape. I am taking artistic license and instead of it being just a street and pedestrian walkway, I plan to also have my trains run across it. In any event, the actual bridge has smallish lampposts on the top of each upright. I am predrilling holes in order to run wires up through the uprights for now and will add lampposts down the road. I did a little research but can't confirm what size wire I would need for a typical lamppost. Probably going to go with HO scale lampposts as the ones on the actual bridge aren't very tall. Any idea what size (AWG) wire I should pre-wire up through the uprights to accommodate whatever lamposts I may choose in the future (be it HO or O). Thank you.
