What does the second street on the street sign mean?

St nd rd th on the road sign can express the information of occlusion meaning, which is easy to carry and hold high. The display distance can reach 600 meters and 200 meters respectively under the illumination of locomotive headlights during the day or at night.

When the basic block stops and switches to telephone block, station attendant can take out the corresponding signs and hand them over to the departure personnel after completing the block with the adjacent stations according to the prescribed procedures. The startup personnel should confirm the complete blocking record in the log, and then insert the signpost to handle the startup.

Street signs should be unified in specifications and design, and their basic structure is divided into three parts:

1. The bottom plate is a blue polygon, which is the base for inserting the blocking sign and the additional sign, with the blocking sign in the middle and the additional sign at the top.

2. Blocking sign-a thick yellow arrow, which is the core of the road sign and indicates the key information that "the previous telephone blocking procedure has been completed and the train is allowed to occupy".

3. Attached sign-rectangle, marked with the words passenger 1, passenger 2 or freight 1, freight 2, etc. , indicating the last digit of the corresponding train type and train number (another scheme uses the last digit of the telephone password that the neighboring station agrees to block).
