I know there's been a few threads on this subject over the years, but seeing as they're all locked, I thought I'd start this one.
With the 18th anniversary of their last revenue-earning run fast approaching (30th December 2002), I thought it appropriate to start a thread on one of the best-known of the early EMU classes outwith the Southern Region 'slammers': the 303s aka 'The Blue Trains' aka AM3s. As the title suggests, you can share your fondest/most vivid memories of these fine units in service, what livery/liveries you think suited them best (or your fave livery on them, period), whether they looked better with their original wrap-around cab windows or the later flat-glass design etc. The 311s are of course also permitted (hence the thread title), given their similarities to their elder sister units and how they worked interchangably with the 303s (much in the same manner as the 318s & 320s do now).
I'll kick things off with this video of the aforementioned last revenue-earning run by BONESS27001, some of the highest-quality footage of 303s in service out there. The creaks, groans, nearly every sound the Gresley bogies make, the squealing brakes.... brings it all flooding back.
Right, that's enough waffle from me, I'll turn it over to you fine folk.
