Here's a link to what just got put together this week on another forum.

This sounds to me very like the first stage of Benny's proposal.

The photo is 1/2 of the plan for one of my peninsulas. The track on bottom right to the loop is based on the UP St Maries RR interchange at Plummer Jct. in Idaho.  The old Milwaukee Road and UP lines both run up a short valley towards the loop and wye interchange at Plummer.

The opposite side will be a passing siding with junction for the branch coming off, and the track at far right continues around the walls to a town. The grey track at left goes to a sawmill on the left 1/2 of the vertical portion of the central peninsula.

The 33rd National Narrow Gauge Convention is coming to Southern California on August 28–31 at the Hilton Hotel in Pasadena. http://33rdnngc.com

Pasadena is rich in railroad history, all of the major rail lines serving California including the Atchison, Topeka and Santa Fe Railway, Union Pacific, Southern Pacific and Pacific Electric "big red cars" were a part of daily life.

Would you be interested in presenting a clinic?

I'm attempting to recreate a major rail and locomotive yard and I was trying to fine lighting similar to the lighting I've seen in pictures.  Specifically I'm looking at banks of flood lights on a high pole.  any help would be appreciated.
