Hi all, I recently acquired LEGO transformer 740 (which appears to be made by Siemens) to power the 725 set I found at Brickmania in Wetteren some time ago. The train runs great, and it really amazes me that all the electronics still work like new! The transformer has three outputs: #1 is marked 0-13 VDC and should be used for the trains, #2 is marked 16 VAC and should be used for electric turnouts, and #3 is marked 3,6 VAC and has a lightbulb symbol. Does anybody know if LEGO ever made any accessories (lights, ...) which could be connected to the third output of this transformer?
