1. Between 125mph and 180mph, depending on the type of train.

2. Varies depending on how many carriages there are but average would be 500 tons.

3. In 1958 most inter-city trains were steam powered but diesel and electric locomotives were starting to appear.

4. Inter-city trains today are diesel or electric powered.

5. A train travelling at 125mph needs around a mile to stop, more if it is going downgrade.

6. A train can't swerve, because its path is fixed to the tracks.

However if it is approaching an obstruction on the track ahead and there is a junction with another track in between, it is possible for the signaller to switch the train to the other track.
