With a digital model railway train detection (block signaling) is an important function. Most often current sensing is used. It is quite reliable and you don't have any (ugly and non-prototypical) sensors in view. The drawback is that it probably also is the most expensive method.

I like to try out some different sensing methods. Just for fun ... but also because I like to use the Arduino for S88 sensor feedback, which can reduce cost by a factor of 5 or more!

This video covers the use of a reed switch and a magnet glued under the loc. Optical detection has been discussed already, see video RMR013 for that.
