Fantastic video as usual!

Wowsers thanks!

Thanks

[@thetrainguy4]

Thank you!

[@davidpemberton9326]

A pretty good explanation

[@Thatonestrangefella]

Now I can be a nsw train driver 😃

[@tamworthtrainnut285]

Also some regional lines such as between Narrabri and Moree, Joppa Junction and Canberra, Orange and Dubbo, Junee and Griffith plus Werris Creek and Armidale are TOW (Train Order Working) sections where the train MUST obtain a special encoded signal or write down instructions on paper where the train wants to go to and if they’ll require shunt access at their destination such as Armidale for the Xplorer train and West Tamworth yard for freight trains, crossovers if another train is in the same area and how the 2 trains will pass each other, at Werris Creek sitting at the Armidale end of platform 1 is signal 1549 which instead of a GREEN light indicating a proceed aspect, a flashing WHITE light is used instead signalling to the driver that they are about to enter Token or Train Order territory and need to obtain a token or a train order from control before proceeding, signs marking the start and end of train order territory have BEGIN TRAIN ORDER WORKING and END TRAIN ORDER WORKING on them

Very thorough and interesting - thank you! Do you work in the railways or is this more of a personal interest? 🤔

[@thetrainguy4]

Personal interest

Reminds me of Taitset’s video

[@jd0192]

Mainline indicators are NOT signals - and they are not found in signalled territory. Only in Train Order territory and they do not provide any authority or permission to proceed. Yellow MLIs do not indicate the next MLI is at stop. They simply indicate that the infrastructure that they are protecting is working correctly, but that there are other frames or points that are not interlocked with that MLI in the area to be on the lookout for. Medium signals in most single track, traditional CTC style lines are pretty much only ever used for early warnings for turning out. Old style loops generally go in on a low speed signal, meaning a caution on the distant

[@thetrainguy4]

Re MLIs I was working off the rulebook.

[@enochliu8316]

According to the rule book: Steady yellow light Points are set for the main line, and warning equipment at a level crossing is in working order. The next main line indicator, where provided, may be at STOP, or Proceed at Restricted Speed: • to the next point indicator or • STOP sign at a terminal location

what should the driver do for each signal?

[@randomonium19473]

@@philhoward4466 I’m a driver so can help with that. As a general: Clear - Track Speed Medium - Prepare for the next signal to be caution. I.e. Slow down appropriately expecting the signal two away to be at stop. Preliminary medium meaning be prepared to stop 3 away. Caution - Next signal at stop. Be prepared to stop at the next signal. Stop - Stop. Turnouts - Prepare to turnout at turnout speed. Medium meaning next signal at some sort of clear and caution meaning next at stop. Calling on - Allowed to enter the block but be prepared to stop as another train may be in the block. I.e. Before the next signal there could be a train. Close up - next signal is at stop and the block after could be occupied. Mainly to get trains closer together in busy suburban areas. Those are the main ones, shunt ahead are super rare, low speed is very self explanatory, as is close up. All of this depends on route knowledge, it’s the drivers job to know where the signals are and what the track speeds are. So there’s not set rules as to what to do when you see a specific signal. The driver must know where they are and what they must do to obey the signal indications.

​@@randomonium19473 -- being x- freight plus inner city driver, I always lived by the motto that the railways paid you stop before the signal, you PAY the railways if you stop on the WRONG side of the signal. PS I'm using my late daughter's tablet, just in case of some confusion.

Qld next

[@kinderjojomojo]

It's 'close' as in together or near. It's not 'close' as in close the window.

[@thetrainguy4]

Not a biggie

[@james.black981]

@@kinderjojomojo as a former Signal Electrician, the term is Close like close the window. Its used in the context of Close up the gap between you and the train in front of you.
