is about to clear like the Toronto subway grade time signals by flashing.

Yes it is possible as i had done it with the Wheel detector. you would just need to replace the the flashing white light with whatever color Toronto subway uses.

It also depends on what signal you're implementing whether its a 2-shot which has an S or is luminated under the bottom signal.
2 Shots will clear basically at any speed so if the limit is like 40 and you're going by at 45+ thats normal(both in the simulator and subway) but the next signal may or may not clear from RED to Yellow or Green depending how your speed is approaching that signal.In the system there are signals like that such as the "dip" section between 103rd and 110th St N/B there is timers and I believe its a GT35 maybe 40 but it clears in the 40's and at the bottom that signal clears at maybe 5 feet from RED to Yellow which is why some train operators fly coming up hitting the mid 40's flying pass 110th and even 116th(in some cases) because theres 2 shot after 2 shot which clear on the post but the less experienced operators brake and brake not knowing.

The 1 Shot Signal which should have a number indicating the allowable speed will only clear at most 5MPH above the posted speed but even that is risking a "trip" but a safe speed would be at or no more than 1MPH above the speed because they change kinda at the last minute(second).

All said in done a 2 shot prepares the operator that he/she may have to slow down depending what section of track they are on and their knowledge of how the next signal clears.Which is why somedays where you know theres timers it may seem slower or faster pending what type of operator is operating that train you may notice a lot of (A) train operators run that timer flying pass Franklin Av which is why they fly in Nostrand its a GT35 but clears on the post of 45.No matter if its run or not most likely the train will fly in Nostrand at least at speeds of 40 because of the downhill and not needing to break at the start of the station because the slight uphill is in favor.

Actual 1-shot GTs have a lunar white light lit, as the signal in this photo shows.

The timer signals with the number are station time signals, which are placed near stations to indicate a signal will clear for an approaching train if the following conditions are met:
* Only the tail end (most distant portion) of the signal's control length is occupied
* The approaching train is traveling at or less than the indicated speed.
[/list]

There has, however, been an intermingling of the timer signal indications, and even varying usages of the number aspect.
For example, at West 4th Street, the home signal on B1 track shows G-G-15 as a speed limit reminder. The same can be said of the home signals at D1 track at 36th Street, and K1 track at Rockaway Boulevard.

Don't forget there some T/O from the (A) line,(D) line like to fly between 59 St to 125 St especially that downhill from 103 street to 110 street which is the best if u have a T/O that like to drive fast.  PS Best train to take it down that hill is the R32 or R46 and it mostly on the T/O on the (A) that like that hill and play with the timers.

Haha true but if you're lucky and have an R-68A (D) or (B) express with the right operator you're in for a treat.Just tell the 46 operators to keep it wrapped or on the post.But the best experience had to be with the 38's and Slants whew old school.
