None of my transformers have these meters. Wouldn't it be neat to add some on? I found this at DIY electronics (http://electronics-diy.com/store.php?sel=kits&sub=pic_voltmeters)
I started looking with this digital amp meter (http://electronics-diy.com/ICL7107_digital_ammeter.php).
John did build his track voltage car too. (http://www.modeltrainforum.com/showthread.php?t=7516&highlight=track+meter)
Something to think about.
I found one for voltage. (http://free-electronic-circuit.blogspot.com/2008/11/universal-digital-led-voltmeter.html)
The ILC7107 is the main ic that is used to operate the digital readout. Around two or thee bucks. One good deal was from Bulgaria, 5 ic's with mounts for under ten on e bay. The component companies may do better.
