Airport train sound effects recorded in London, Stockholm, Bangkok, and Toronto, mostly onboard, covering high-speed, electric, and diesel rides with door chimes, PA announcements, starts, stops, and crowds.

High Speed sound effects, mostly motorbikes going past faster than seems sensible. Superbikes and racing bikes recorded trackside, ripping past the mic and fading off down the straight. Proper speed. Then a very different kind: fans spinning up through their speed settings, from a gentle domestic whirr to a big industrial roar.
The pitch drop as a bike passes is what sells speed, and the faster it goes, the sharper the drop. The bike recordings catch that from several spots around the Race Track, close up and far off. The fans are a quieter idea of speed, handy for machine rooms and anything that needs to whirr.
