The hidden side of efficient railway operations,the maintenance,the supplies,and the garbage collection.
Interesting stuff.
Express trains getting essential maintenance on brakes and being returned to service within 6 hours.
The making of dinners for thousends every day.
And the cleaning of bedsheets turned into an industrial process.
There is an overlap at the end of the clip but all in all it is nice watching.



Respect to all those people,irrespective of their rank,to make this possibble.
