Motorized Switch (for lefthand switch #2861) This is an improved version of TSwitch2. The base has been beefed up a bit, a second 4x6 plate has been added to the roof, and I've eliminated three 1x1 plates that I think were weakening the grip. If you build this, I recommend using transparent panels as shown in the photos since these panels are made of a stiffer plastic than the opaque panels. The panels I used happen to be from set 4561 (Railway Express). The tswitch4.ldr file uses 2866.dat (yellow switch lever) which can be obtained here (Thanks Ludo!): http://news.lugnet.com/cad/dat/parts/?n=4471 Mark Riley markril@hotmail.com http://home.surewest.net/markril/lego/index.html
