This photo was submitted into the Rp photo group via flickr (an easy thing to do if you wish to see your photos on the front page) and I got to thinking.



How does changing to channel 37 make the crossing work if that is in fact what the sign suggests?

It could well be as simple as reminding the driver of which radio channel they need to call the signaller who will activate the crossing and clear the train to proceed. Like most signs for drivers, this would be just a reminder of what they already know as part of their route knowledge.

Automatic level crossings are a pain in the rear end for areas around major yards with shunt movements etc.

The select route details have caught my attention what do you propose they mean ?

Pilot activated lighting springs to mind. Pilot double clicks on the comms frequency to switch on tarmac lights of an unattended airfield.

No need for signaller (or, in aviation, air traffic controller) in an environment of sparse movements.

Do we have anyone from Tasmania on the forum?

Could the same be for the crossing then ?

Freightgate, my thought process is that, having received and read back a train order, driver could control both the switches and the crossing with two simple radio activities.

Technically possible (as with aviation PAL).

Does it happen this way?  Don’t know, hence the enquiry about someone from Tasmania with knowledge rather than (my) speculation.

Certainly Tasmania does seem to have moved towards greater use of radio technology (as reported in relation to the cement train incident some months ago) for shunting etc.

Interesting information available at Tait Communications- supplier of the digital radio system embedded in Tasrail’s train control system.

In short, driver can request and receive permissions to move to another section of track - effectively an automated train order delivered by radio.

Probably not that much different to the ICAPS across the Nullabor. You can select the facing point route setting on the fly when approaching, depending on if you transmit a request to the interlocking. In this case, instead of a single frequency determining multiple responses, multiple frequency options elicit specific routes.
