Railroad emergency notification — Delaware Permit Test

Railroad emergency notification on the Delaware permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Calling the Emergency Notification System (ENS) number posted at a crossing is the best way to reach the railroad about a problem at the crossing or something blocking the tracks.

A stalled truck on the tracks is only cleared in time if the railroad hears of it before the next train.

Utilizing the ENS is the best and most efficient way to contact the railroads if there is a problem at the crossing or if something is blocking the tracks.

Delaware Driver Manual, p.83

A crossing's ENS number is typically on a blue sign on the crossbuck, or nearby.

A driver who has to hunt for the number wastes the minutes a train needs to brake.

The ENS number is typically located on a blue sign on the actual cross buck or it can be found in the vicinity of the crossing.

Delaware Driver Manual, p.83

The DOT number on the ENS sign tells the dispatcher exactly where the crossing is, so trains heading there can be told to stop or slow down.

A caller who can only say "the crossing near the farm" leaves the dispatcher unsure which train to stop.

The DOT number tells the dispatcher exactly where the grade crossing is so they can notify all trains moving in that direction to either come to a stop or slow down before reaching the crossing.

On the test

A car is stuck on the railroad tracks. What is the best way to tell the railroad?

Call the ENS number at the crossing. A stalled truck on the tracks is only cleared in time if the railroad hears of it before the next train. Delaware Driver Manual, p.83: “Utilizing the ENS is the best and most efficient way to contact the railroads if there is a problem at the crossing or if something is blocking the tracks.”

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
