Interesting concept. Likely to be of greatest utility for those with larger layouts where the cost of a conventional section reading approach becomes rather steep in both implementation effort and cost. Will it be unrestrictably scaleable? It might need real care in magnet positioning to avoid aliasing problems is one immediate suspicion I have. Between random bad reads and quasi random movement of magnetic fields - the motors of the locos, ferromagnetic components in moving mechanisms, wheelsets and ballast weights - the magnet placement may well need very careful installation mapping for truly robust performance.
(I have been there many years ago with contactless mapping using RFID, and what looked very promising in principle unfortunately collapsed hopelessly at the scale of the proposed application.)
