I remember during Covid watching videos of Stratford and I was fascinated by the variety. Slightly off-topic but the South Western lines near me are also soon to see the end of variety with the 701s coming in, though the transitional period has been quite interesting with 450s, 455s, 458s (both refurbished and unrefurbished), and the 701s all on metro services.
Enjoy while you have it. I wish I'd got out and recorded some videos of local places with the old trains trundling along even just in the background adding to the atmosphere of the place. I took them for granted, just as I took the old slamdoors for granted. Though admittedly some of our classic traction disappeared during lockdown, there was no way I could have envisaged my Dec 2019 trip behind a Class 90 followed by the Class 360 connecting train would have been the last time I'd have either for traction.
