[DCC] What is Positioning Reporting?

[RedLeader]

Hi,

Still deciding in my new DCC system. It has come to my attention, that all mayor DCC sets have a positioning report, eg: railcom. What is that?, because in Tony's table, Prodigy Advance has none, where everyone else does.

Not all DCC systems have this, only the most expensive systems. Position reporting is a feature that reports back to you where the train is located on the layout, and is applicable only to transponding decoders, which are a recent development used by only a few manufacturers. Unless you really must know where your train is located because you can't see it, you don't need position reporting.
