[quote user="BroadwayLion"] [quote user="Bucyrus"]The total solution for securing unintended trains would be a power brake acting on all cars simultaneously from a single control that could be locked with the security of the locking system detailed in the BRT report. [/quote] Well, this is all well and good, and it applies to trains. But it cannot apply to railcars. Railcars must be moved by plant personnel for loading and repositioning equipment. Once a car is set out from a train, its air pipe is open to the atmosphere, and the pressure tank is bleed so that the brakes will release so the car can be moved within a plant. Once here only hand brakes can hold the car.[/quote] I am proposing the type of powered, all inclusive, and simultaneous parking brake only for the new breed of high performance, crude oil unit trains that will soon be the law of the land.  You set these parking brakes by setting the air brakes and then throwing a switch in the cab to set the brake locks.  You release them by throwing the switch to release.  Once you bring all this control to one switch, you can connect that switch to any number of different authorizations that may lock or unlock the switch.  The switch will be wired to also tell the world whether it is locked or unlocked. You can still equip these special trains with hand brakes if you want to, but these unit trains will be a semi-permanently coupled, non-interchange consist, so there is no need for hand brakes for dealing with individual cars or cuts of cars.  The main point is that these new oil trains will not rely on manually winding up several hand brakes, or making sure they stay wound up in order to prevent the trains from wiping out towns.
