OK, so how is that crossing designated and identified?
I am sorry, I figured everyone here are railfans or railroaders and have a basic knowledge of the subject. Sometimes we old farts take too much for granted. Basically, if you look at a railroad grade crossing sign or crossbucks, the one of the right as you face the tracks and is facing road traffic, you’ll see there is a tag that identifies the grade crossing by railroad, mile post, road name, some other information, plus an 800 number to call in case of problems or questions. The plaque is about three or so inches wide and maybe eight or so inches high, usually off white with black letters. I’ve seen some being of reflective material but that’s not the norm.
Let me see if I can make the question clearer. In the case of the NEC crossings, what information is given–i.e., what is the name of the railroad (OK, I know it’s Amtrak in this case), the division, the mileage?
What specific crossings are you talking about. Any specific crossing is marked as described above, you can drive to it and read the posted signs. If you cannot get to the crossing you can probably find the information on the AAR or someother website if you google it or state the specific crossing here and someone with an Amtrak ETT or other material can answer.
No worry on the NEC between New York and Boston. Five crossings still exist between New London CT and Westerly RI, all protected with 4 Quadrant Gates. Speed reduction to 89mph or less do to crossings and bridges are in place. Once you clear Westerly RI, northbound, you can open up to 150mph. (Acela)
