In just one day on Pennsy’s 4-track mainline across Pennsylvania one could witness the passing of over 50 named passenger trains in the 50s… interspersed among 100 regular freights and coal drags.
Pennsy owned (and built most of) over 10,000 steam locomotives.
When Pennsy liked a freight car design (like the H21a hopper), they built 30,000 of them.
When Pennsy decided it liked the I1 class 2-8-0, it built or bought 598 of them.
Until its death in 1968 Pennsy owned 10% of the freight cars in revenue service across North America.
Pennsy bought and cleared dozens of blocks in midtown Manhatten and proceeded to build a 2-block-wide station and tunnels under the Hudson River… before 1910.
Pennsy operated the most electrified trackage in North America.
Pennsy owned the busiest commuter railroad in the world (the Long Island Rail Road).
Pennsy designed and built the GG1 and the K4.
Pennsy operated the first all-steel passenger fleet.

Pennsy’s Enola Yard (across from Harrisburg) was the world’s largest classification yard. Conway Yard, west of Pittsburgh, was the nation’s largest automated hump yard.

By the way, Pennsy pre-dates the UP and CP by a wide margin - 1848. It was, of course, merged out of existance in 1968.
Pennsy wasn’t the standard other railroads went by. Pennsy was its own standard. For example, the 573 L1s class 2-8-2s, 598 I1s class 2-10-0s, and 475 K4s class 4-6-2s shared identical boilers. PRR standardized everything… to itself.
Even today, the Northeast Corridor, America’s only high-speed rail network, is a vestage of Pennsy. Most of it was constructed 100 years ago! Back then, 4-4-0s and 4-4-2s routinely hit 100 mph on the Corridor.
