Is that an issue with the architecture of the DC Metro, or just the design of its "accessories?" Glass walls to prevent people from falling into the tracks weren't a thing when most subways were constructed in America.

It's possible to retrofit the DC Metro to keep its (arguably) beautiful ceilings [0], while still making it safe and navigable for commuters.
