LGB Model Train – Living Desert Zoo – Palm Springs, CA Model trains became a part of The Living Desert in 1998 during the annual WildLights holiday program from the day after Thanksgiving until the New Year. Initially, it was decided that although the trains would operate only in the evenings as part of WildLights, basic layout of track would remain in place; only the trains and buildings would be stored. However, because of the popularity of the display, the trains started running full time during the regular park hours beginning January 1, 2001. The trains are referred to as “G” scale, which is approximately ½ inch to the foot or 1:22.5 inches, about twice the size of Lionel trains. Although not the largest model scale train, it is the most popular “large scale” train. The locomotives, rolling stock, track, switches and most of the equipment are made by LGB. In fact, the letters “LGB” stand for Lehmann Gross Bahn or Lehmann’s Big Train.
