My first attempt at capturing a video file of my 0 gauge layout.
The trains running are a Lionel GG1 pulling five Lionel passenger cars, Lionel 224 2-6-2 tender loco on freight car duty and a French Hornby 0-4-0 tender loco, in PLM livery, with three cars. The loco in the background (higher level) is a Kusan pair.
Second attempt.
The trains are, on the outer loop, a pre war Lionel 261 pulling a rake of four passenger cars (three 607s, and 608), centre loop a Marx Rock Island AB lash up pulling freight and, inner loop, a Bing 0-4-0 German outline loco pulling three four-wheeled passenger cars (probably Bub).
