Train Scheduling and Graphs

The video explores the early days of railways, highlighting the lack of structured timetables and safety measures. It introduces the concept of the train graph, invented by Charles Ibry in 1847, which revolutionized train scheduling by visualizing time and distance. The video explains how this method is still used today, including a case study of its application in Singapore's MRT system to solve a power issue caused by a rogue train.

What was the common attitude towards train scheduling in the early days of railways?

• Casual and flexible scheduling

• Strict adherence to timetables

What does a crossing of lines on a train graph indicate?

• Trains are on different tracks

• Trains are at the same station

• Trains will collide on the same track

• Trains are running on time

How can a train graph help in scheduling trains?

• By calculating fuel consumption

• By preventing line crossings

• By visualizing train routes

• By showing train speeds

What is a key feature of train graphs that helps avoid collisions?
