Signals For Amtrak And Mbta Line.

Here we go. These are NORAC operating rules. Signals are found to the right or above the track. There are going to be a lot of posts. L is lunar white/ R is red / Y is yellow/ G is green and * is flashing.

281- Clear (G or G over R)




281b - Approach Limited ( Y over *G)

 

281c - Limited Clear (R over *G)


282 - Approach Medium ( Y over G)

 

283 - Medium Clear ( R over G)


285 - Approach (Y or Y over R)


286 - Medium Approach ( Y over *R)

 

287 - Slow Clear (G on dwarf signal)
(2 x L vertical on position light)

 

288 - Slow Approach ( *Y on dwarf signal)
(2x L 45⁰ angle position light)

 

290 - Restricting (L on dwarf signal)


291 - Stop & Proceed ( All R with number )

 

292 - Stop ( All R no number plate)

And those are the ones in the map.

 

It would be awesome if you could also include what each signal actually means, still, pretty cool nonetheless.

 

Oh here you go.

Limited clear means limited speed
Stop and proceed is as it sounds.
