Route Florida Tri-rail: Miami Airport - Boca Raton

Does Anyone know what these yellow signs with the letter D on it mean on Some signals?

 

Noticed not every crossing has whistle boards proceeding them and cars are going through some crossings too.

 

I think the line uses NORAC rules. If that is the case, the D means:

DISTANT SIGNAL MARKER
Visual reminder to push-pull trains that Rule 504-B applies in the block governed by this signal.

Rule 504-B reads as follows:

Push-Pull Trains Making Station Stops or Slow Movement After Passing Distant Signal

If a push-pull train that has passed a distant signal makes a station stop or reduces speed to less than 10 MPH, it must:

1. Approach the home signal prepared to stop,
AND
2. Not exceed 40 MPH, unless governed by a slower speed.

The train may resume the speed authorized by the distant signal when the home signal is seen to display a proceed indication. If a push-pull train makes a stop other than a station stop in any block, it will be governed by paragraph (A) of this rule.


Rule 504-A:

Trains Making Stops Other Than Station Stops

If a train that has passed a block signal stops for any reason other than a passenger train
making a station stop, it must proceed at Restricted Speed. The train may resume the
speed authorized by the last signal received when:

1. The next signal is seen to display a proceed indication,
AND
2. The track is known to be clear to the next signal.

 

Thank u for the clear explanation I Will get that to mind passing it in the future !

 

As anyone been able to activate all the safety systems for the F40ph and the rotem cab car.

 

A handful of AI services with the GP49 don't have headlights on. The ballast train specifically but I've seen a few passenger services without lights

 

Me neither, the scoring doesn't work for both of these
