I’m at a point where I need to build a helix and trying to decide the direction to take. Whether it would be Atlas/PECO flex track + whole shebang; or KATO Unitrack, or even Tomix Fine Track (very pricey). Over at nScale.net forums, I made a post with some rough estimates of costs for my case and I thought to post it here on my build blog for everyone to see.
A two part video from a PECO Instruction DVD circa 2000, with good advice for anyone entering the hobby.
Dated by timeless information covering the whole process from scale selection, layout design, benchwork construction, laying trackwork, wiring, scenery as well as operating.
