Signal Aspects & Indications

Explanation
The indication for "Stop and Proceed" is to come to a complete stop and then proceed at a restricted speed. This is done until the entire train has cleared all interlocking and spring switches if the signal is an interlocking or CP Signal. Additionally, the entire train must have passed a more favorable signal or entered a non-signaled DCS Territory. In CSS territory, trains with operative cab signals must not increase their speed until they have traveled one train length or 500 feet (whichever distance is greater) past a location where a more favorable signal was received or where special instructions or letter G grade marker or letter R restricting marker with a number plate are displayed. Freight trains may observe the signal as if through restricting rule 290 were displayed.

Explanation
The indication of Restricting Verbatim is that the train must proceed at Restricted Speed until the entire train has cleared all interlocking and spring switches. If the signal is an interlocking or CP Signal, the train must also wait until the entire train has passed a more favorable fixed signal or entered non-signaled DCS territory in CSS Territory. Trains with operative cab signals must not increase their speed until the train has run one train length or 500 feet, whichever distance is greater, past a location where a more favorable cab signal was received.

Explanation
This signal is indicating a slow approach.

Explanation
The indication to Slow Approach is to proceed prepared to stop at the next signal. The train should maintain a slow speed until the entire train clears all interlocking or spring switches. After that, the train can increase its speed to medium.

Explanation
The signal in question is called the "medium approach."

Explanation
The indication of medium approach is that trains should proceed but be prepared to stop at the next signal. Trains exceeding medium speed must begin reducing their speed to medium as soon as the medium approach signal is clearly visible.

Explanation
The signal name is "approach".

Explanation
The signal indication of Approach is to proceed prepared to stop at the next signal. Additionally, trains exceeding medium speed must begin reducing their speed to medium speed as soon as the engine passes the approach signal.
