Re: 33 inch wheels

Except, according to White, they started off big, tried small for a short period, and ramped up to 33 pretty quickly. They compensated by making the wheels as light as possible (reducing the mass moment of inertia), apparently.

No reason why they picked 33 over 30, 32, 34, or 31.831 though.

. . . In the early days with
wimpy locomotives small wheels were a necessity. As locomotives became more
powerful, larger wheels became more practical to operate.
