Hello Clem,around my engine house which has several tracks and sidings I used the Lionel 6-37995 Lighted Telephone Poles.
With these poles spaced out they lighted this area very realistically.
To me the light from each pole is just enough to light an area without being to much light.
They don't take much power to operate either.
