How does the engineer keep a defined speed constant with a diesel engine if there are only 8 notches available?
If e.g. notch 4 with 5 car is good for 30 mph and he picks up one empty car is notch 4 not enough power anymore but notch 5 would be possible too much to proceed with 30 mph. Is he constantly switching up and down to maintain a constant speed? A longer train might be less sensitive but how about a very short train and a powerful engine?
