Why are trains faster than they were in the olden days?

Trains are faster today due to advancements in technology, including improved materials and engineering that allow for lighter, stronger trains. Enhanced track design and construction, along with better signaling systems, enable higher speeds and more efficient travel. Additionally, the introduction of high-speed rail systems in many countries has revolutionized train travel, allowing for speeds that were previously unattainable. Overall, these innovations contribute to significantly reduced travel times compared to older trains.
