I watch some shit on youtube. I wasn't a train driver in 1991 and I'm still not. So this video is not relevant to me. Yet I sat through all 10 minutes of it.
What I don't get is how it's advised to start with a full service brake application as well as brake earlier (that one actually does make sense) in advance of a danger aspect or a buffer stop, given that they've established these conditions often pair with low rail adhesion. I mean sure the wheel slide protection system would still do a way better job than you manually applying and releasing the brakes, but surely the braking distance would be reduced when the wheels can't lock up at all. Then again I think I'm taking these old videos way too seriously.
