While through manifest trains are stable length locals pick up and set off cars along the way - and historically there was no reliable way you'll know exactly how many cars you'll switching in and out. Even today you can see conditions change after a local leaves a yard and before it reaches say an interchange between two railroads or a major shipper.
- thriftwy 9y agoWhy don't they make an app to track trains' length? Indeed I have hard time imagining an unaccounted car running on public rail.
- falcolas 9y agoHuman error. These kinds of things happen all the time - packages going through UPS/FedEx get lost, containers on ships are lost (i.e. put in the wrong stack or fall off into the sea), containers in ports are lost/hidden... There's a lot of rail cars in the US by itself. And while they are already well tracked, mistakes happen.
