Read it again more carefully. They were suggesting, perhaps not directly enough for some, that these long trains are too long, and increase derailments. Because:
- they are harder to start and stop, because size. One mistake.. Shorter trains are easier to control, physically
- Crews are exhausted by these trains because they take too long in infrastructure not built for them (1940s yards), and adding to waiting time, making it much slower to add / move carriages / trucks around, and other logistically disproportional wastes of time
- The trains are too long for communication purposes too. radios don't have the distance. Safety and important messages get missed
