I know of a new set of drivers diagrams that was brought in at one particular TOC because a consultancy company claimed their algorithms could do the diagrams much more efficiently and save some diagrams per day so less drivers required. It was ditched within couple of weeks because the computer algorithm didn’t have scope for all the factors associated with train planning that an experienced planner knows to take into consideration and allow pathing time for.
Royal Mail did something similar when they replaced a postie on a bike doing one round each with two posties sharing a van doing two rounds between them. The problem was some posties walk much quicker than others, so pairing them up meant the quick walking ones were slowed down, plus on short distances vans are quicker than bikes.
