Here is a system that I currently use, it supports up to four cameras. This one has outdoor cameras but smaller indoor models are also available. The video quality is okay when in 4 screen mode but clearer in single screen mode. The out door cameras have night vision which may be useful if you run your trains in the dark. The monitor is rechargeable and portable or it can be mounted stationary and includes a kickstand. Latency is usually about 2 to three seconds which is good for your purposes but not great for live video. Oh, it also has a video out port so the small display can be output to a much larger display with a composite video in port.
Also, many of the cheapo wifi camera systems available from Amazon will also work. They'll come with a nice app that will allow you to monitor a single feed (some will allow multiple feeds) at a time. They might be a little harder to setup but they are cheap, usually anywhere from $20 to $50 per camera.
