History of RFID for Model Railways

A short history of RFID for model railways.
Please contact me if you think other things need to be added, to give other hobbyists a more complete view.

History

Doing web searches for RFID for Model Railways (or Railroads) throw up some results, and hobbyists seem to have been experimenting from at least 2009.
The first significant presentation seems to be "RFID in Model Railroading" given by Seth Neumann and Chris Drome at the 2013 NMRA convention in Atlanta. This is the system they described in December 2014 Model Railroader magazine.

There is a  video  here of a RFID system by Steve Davis, based on the above.

It is well worth reading this article, and I am grateful to Seth Neumann for giving permission to download the article here.

MERG and RFID

MERG has been doing some fine work in RFID, making the IDLA12/IDLA20 readers available, and doing a concentrator for up to 8 readers into CBus.  There has been a lot of discussion on the forum on how to implement it, and recently much work has been done on trying to use the RC522 as a reader, with some success.

Summary

For whatever reason, RFID seems not to have taken off as a mainstream technology for hobbyists.  There are obviously quite a few hobbyists working away on it, but they all seem to be trying to adapt technology used in other areas, and applying it to modelling.  To my mind, RFID has great potential, as it can be used not only to identify rolling stock, but also for block occupancy, feedback for automation systems, Train-on-Track-Indication - all of which need separate systems at present.  Hence this attempt to design, from scratch, a system specifically targeted for model railways.
