Different manufacturers calculate it differently, with some being quite optimistic and others being more conservative. In some of these more conservative cases, the best case actual throughput sometimes outweighs theoretical throughput.How can the actual be higher than theoretical? Theoretical is an unrealistic best case based on loading every seat and dispatching a train at the minimum safe interval consistently for an hour, surely?
I guess so, yes, but that’s often, perhaps incorrectly, referred to as “theoretical throughput”.So 'manufacturer quoted throughput' rather than 'theoretical throughput', then?
I can't speak for the 90s but by the early 00s they absolutely were not dispatching trains with disembarking guests still on the platform. As @rob666 says there used to be more staff and one of the things they used to do more was hussle guests along.Thing is, back in the 90s and early 2000s you could dispatch trains with guests still on the platform, didn’t have to worry about keeping guests behind locked exit gates etc plus loads of other health and safety things which really do slow down dispatches. Staff get the flack for a lot of slower throughputs these days but most of the time they’re dealing with pre dispatch, non guest loading processes rather than just getting guests loaded.
