I have a 734 package unloading car, an oil barrel loader, a mail pickup car and a saw mill. They all work great. When I had a stockyard and cattle loading car, they worked fine also. I got tired of them, so I sold them.

However, I can tell you from experience: I have my transformers in phase with the base posts all connected and the output posts going to a bridge rectifier, then to the track. I have five transformers connected this way for five different blocks. Most of my locos have bridge rectifiers in their tenders and I use a DPDT switch to reverse polarity and reverse direction of the loco. Even the locos I haven't gotten around to converting yet work just fine, using the reverse unit for direction control. Unless some one knows otherwise, I consider this to be a DC common rail system. I also use a prewar 1282 transformer on AC for my accessories. I have found this transformer can deliver up to 25V. I dial up what I need to make the switches snap. Cheaper than buying a 30b. The AC comes back on the base posts with the DC and it doesn't seem to matter to the transformers, trains or accessories. > > Hope this helps, > -Tim > ----- Original Message ----- > From: [EMAIL PROTECTED] > To: [EMAIL PROTECTED] > Sent: Friday, October 25, 2002 3:28 PM > Subject: [S-Trains] another DC common r ? > > Here is another question I have about DC common rail systems: how do you > hook up multiple power sources? > > If you use only 1 power source to power a large toy rr, it must have a lot > of amps, potentially enough to weld pickup wheels to the rails and unleash > major destruction during shorts caused by derailments.
