Isolate the track into blocks of approximately 1 1/2 train length sections, wire each block to a double-throw switch, and wire a transformer into each side of the switch. This gives you what is called two cab block control.
Block control can get complicated and expensive (those switches aren’t cheap), so if you are planning an extensive layout you might consider DCC. It’s much cheaper to start with DCC than to start with block control and then switch over.
There are many good books on layout wiring, it would be well worth your time and money to invest in one (such as Robert’s E-book) because it will answer questions you haven’t even thought to ask yet.

Voltmeters are pretty easy to find inexpensively at home centers, Radio Shack, Harbor Freight, etc.
When measuring direct current with a voltmeter the reading will be negative with the probes touching the terminals on the transformer one way. Reverse the probes to opposite terminals to get a positive reading. Voltage should range from 12 to 18 volts with the throttle full on.
IF you decide to use two transformers, you will have to isolate the track to two separate sections. DO NOT connect two transformers to the same section of track.
If your track is mounted on a layout, consider running 12 AWG buss wires under the layout connected to the transformer outputs and use feeder wires to the track at roughly three-foot intervals. Track is generally a poor conductor of electricity.
Hope this helps.
