Train announcement in Tokyo

I was on a Toyoko Line (connecting Yokohama and Tokyo) and there was an announcement by a train conductor (which is very rare) : "We will soon arrive at Yokohama. Everybody, otsukaresama deshita (good work for the today).  If each one of us's small effort comes together, it will add up to a big one. Let's be strong and work together tomorrow. Please go home safe." The atmosphere inside the train got softened and warm.
