The term "slam-door train" often refers to electric or diesel multiple units with manually operated doors. Such trains like Class 411 had been common for decades, but they dwindled due to safety concerns, and they were scrapped even though some of them were less than 30 years old. The "Slammers" were withdrawn mostly by the mid-2000s, but coaches with slam doors still remain on main line.

In the same year, I was also surprised to see a genuine Slammer at Waterloo, whose door was opened by passengers even before the train stopped.
