Chatsworth Accident Details Kept Hidden - Trains Magazine

I find it frustrating that there is yet to appear no diagram to scale showing the location of the Chatsworth collision, signal towers, switches, station, etc.

There is also no information given on what safety and signal equipment was implemented trackside or in the respective locomotive cabs.

No information yet on what kind of CTC was in operation and what alarms were sounded when the Metrolink train passed a red and drove through the points onto the single track porition of the line.

No photo of the signal tower the Metrolink train apparently passed on a stop/red.  It would be interesting to know what kind of signal it is, how many heads are displayed and how many lamps are in each head.

All of the above should have become available by this time.  Instead, it seems it is being kept under wraps.  One shouldn't have to wait a year or more to learn any of these facts now.
