It's not enough to couple the cars together with drawbar "knuckles." The brake lines have to be connected as well. Not too difficult, but requires stepping between each pair of cars and fastening the hoses together with a twist. The brake check requires the entire trains brake system to get pressurized to first set the emergency brake chambers one each car . . . and then (via an ingenious valve system) to pu enough pressure in the line from engine-to-rear-end to then release those brakes. It's amazing how simple, complex and functional and it is not that different now vs. 80 years ago. Small differences like way more unit trains, yard air pressure (to prep the trains before or without an engine) and electronic controls. Safety, durability and efficiency are always the goal.
Too bad for all the fallen flag railroads. The merger of Pensy and New York Central forming the Pen Central doomed both fallen flags. It became increasingly difficult for railroads after the end of the 1950. I model a fallen flag railroad, the Central of Georgia since I used to live in Georgia. CofG was purchased by Southern Rail lines in 1962, and then Southern was purchased by Norfolk Southern after acquiring Norfolk Western, forming the parent company. Cheers from eastern TN

Hi Dave Here I am wanting to model a small freight yard in HO Scale I like your video thanks for putting them up Dave
Teletypes? Two-way radios? Diesel locomotives? My gosh, what WILL they think of next?
you had to ask didn't you? 😂😂

Isn’t it still done the same way basically?
Too bad we don't have all that industry here anymore.
That was real railroading,not like today.
Fascinating movie
Awesome
So many human computers working in unison. Watching these films convince me of one thing - I am not smart enough to work here
Im just like everybody else
Depressed and lonely?
@@whiteknightcatI don't think most people are depressed
@@danikoo582 LOL. I was just going by the odd videos on their channel.
