Tracking trains on "TRAIN_MVT_ALL_TOC"

[Stefan Safranek]

I am working on a geospatial and time-series project using the "TRAIN_MVT_ALL_TOC" datafeed to track individual trains. I was using the “train_id” from this datafeed as an id for the individual engine however after 48hours I ended up with 45,000 trains. This number seems way to high. Currently, I am training to use the “train_uid” from the “Train_Activation” message to try and track the individual engines. Since the “train_uid” is the id for the schedule being activated I am concerned that this isn't a unique identifier for the engine (can different engines have the same sechedule over time?).

Any help would be greatly appreciated.

Thanks!

Stefan

Hi Stefan

You're looking at the wrong set of data - what's in the train movement feed is train *services*, rather than actual rolling stock.

The rolling stock allocation data is held in various other IT systems, none of which are currently open :(
