Throughout the years, ingenious railroaders devised all sorts of tactics to accomplish this.  But every one of those methods revolved around something called "block wiring."  In this technique, the railroad layout is divided up into separate electrical blocks, each of which controls only one locomotive.  Called "cab control," a cab -- or throttle -- was then used to control each individual train.  Arrays of various selector switches connect the blocks.

The best form of this method is called "progressive" cab control.  One of the trains runs on the layout.  The connection between the cab and the block is automatically changed from one block to the next using relays.  The first block is then free for another train to use.

I'm 99.9% sure he was talking about couplers on his rolling stock.

Yes I do. You have anything in mind? I'd rather go find some lilies. lol

I think you should investigate the difference between scale and gauge.     Report back what you find.

Hello, here's something will help. Scale means exactly what the name implies.  The model you're using or building is a "scaled down" replica of the life-size version.  Gauge, although sometimes spoken in the same breath as scale, is slightly different.  Gauge measures the width of the tracks on which your train runs. 

Cheers!
