Galactica is an absolute arse ache to get high numbers on, seats out of use, people faffing on offload, not having bay loaders, leg flaps not closing fully, locking pins being stiff or needing rechecks not to mention having to bringing crafts up & down with rechecks. We with a cracking team rarely got over 1000pph sadly
Nemesis was a breeze usually no comments
RMT never exceeded 600pph in my time, that's with all the carriages attached btw. Major issue that slows it down is the exit turnstile, kids,, bags and teddies get caught and slows everyone down, on quiet days we'd use the RAP gate to expel everyone, so much quicker
Unfortunately it all comes down to Towers listening to the staff and aiding them, for 3/4 seasons we would contribute ideas that would've increased throughputs but if it involved finances that was the end of the convo. Extra staff on galactica, exit airgate on RMT along with other suggestions all shot down. Shame but alas
