Re: Empty/load sensor for braking

Virginian in particular seemed to like E&L brakes in its earlier years, opting for them on its WW1-era G-2 and H-4 classes (and removed them around 1931), plus the battleship gons. Most railroads tried to avoid them, though, due to the added complexity and expense. When the AAR made them a "Recommended Practice" in 1936 for cars with a rated capacity more than 3x their light weight, N&W took the simple expedient of relettering its hoppers from 115,000 lbs to 100,000 lbs to avoid equipping its cars with E&L brakes.
