QUOTE (dwb @ 5 Aug 2008, 18:31) <{POST_SNAPBACK}>Here's a couple of suggestions:-

Try LDT for either ready to use or a kit. Use this link to get direct to the English page of their website.

Or join MERG (website here) and buy their section detector kit.

I think both of these work on a current detecting principle, so are suitable for DCC only.

The LDT unit will only operate via a feedback bus so isn't suitable for a simple visual indicator. Typically for MERG they have several kits that do much the same job. I think the simple ToTI was designed for DC but will work with DCC, it is probably easiest to hook up to an indicator light but needs some complicated power supply arrangement. There is also the DTC8 about which I know very little, I use the LDT units rather than either of the MERG ones.

If you are getting into optical detection there are also detectors (from Heathcote Electronics I think) that bounce an infra-red beam off the bottom of the rolling stock. The big issue with optical is that they detect the presence of a train at a certain location, unlike the current detector which detects that there is no train in a section. Of course with current detectors, unless you just want to detect the loco you need to fit rolling stock with resistance axles.
