Why Do Trains Run Faster at Night? Unveiling the Reasons Behind the Speed Boost!
At night, trains tend to run faster and more smoothly compared to daytime. There are several reasons behind this:
Fewer Signals and Less Traffic
During the day, train networks are busier with many passenger and freight trains running on the tracks. This requires frequent signals to regulate train movement. However, at night, the number of trains decreases significantly. With fewer trains on the tracks, there are fewer signal stops, allowing trains to run at a consistent high speed without unnecessary delays.
Clear and Continuous Green Signals
Since there are fewer trains at night, signals remain green for longer periods. In the daytime, signals frequently change to manage heavy rail traffic, often requiring trains to slow down or stop. At night, the reduced congestion ensures that signals allow uninterrupted movement, enabling trains to maintain higher speeds.
Less Maintenance Work
Railway maintenance is usually carried out during the daytime when visibility is better, and workers can perform repairs efficiently. Since maintenance activities slow down train movement, their absence at night allows trains to run smoothly without interruptions.
Cooler Temperatures Reduce Friction
Temperature plays a significant role in train speed. During the day, railway tracks expand due to heat, which can sometimes cause slight misalignments and force trains to slow down for safety reasons. At night, when temperatures are cooler, the tracks contract and stabilize, creating a smoother surface for trains to run on. Additionally, lower temperatures reduce friction between the train wheels and tracks, allowing the train to move more efficiently and at higher speeds.
Fewer Stops at Stations
Daytime trains often stop at many stations to serve local passengers, which naturally slows down their journey. At night, however, many smaller stations are bypassed, leading to fewer stops and a higher average speed.
Priority for Long-Distance Trains
Long-distance trains running at night are given priority on railway tracks to ensure they stick to their schedules. This means they experience fewer delays and can travel at a faster speed without frequent interruptions.
Freight Train Scheduling Benefits Passenger Trains
Freight trains usually operate at night to free up tracks for passenger trains during the day. This scheduling reduces congestion on the railway network, allowing both freight and passenger trains to move efficiently with minimal delays.
In summary, nighttime train operations benefit from fewer signals, less traffic, continuous green signals, reduced maintenance, stable tracks, and fewer station stops. All these factors contribute to smoother, faster, and more efficient train journeys during the night.
