Tons per operative brake
Posted by greyhounds on Sunday, April 12, 2015 11:34 PM

If a five platform intermodal car is equivalent to three operative brakes and a three plaform intermodal car is equivalent to two operative brakes, how many operative bakes does a two platform articulated auto carrier equate to?

I'm just your average, everyday, uncivilized howling "anti-government" critic of mass government expenditures for "High Speed Rail" in the US. And I'm gosh darn proud of that.

  How many brake systems are on the car?  That 5 platform car has 6 trucks, and 3 brake pistons being driven.  The 3 platform car has 4 trucks and 2 pistons driving the brake shoes.  The 2 unit auto carrier has 3 trucks, but how many brake pistons are driving the brake shoes on the 3 sets of trucks under it?  I have not looked, but I suspect someone here as 'looked' under one of these cars.  Maybe a copy of the railroad's special instructions has your answer.
