The London Underground opened over 150 years ago, and yet manages to keep up with capacity requirements, open new lines, and generally is incredibly reliable. I&#x27;d be surprised to get to a platform and wait longer than five minutes for the next train.<p>Part of that is because they don&#x27;t run 24 hours allowing maintenance to take place at night, but I think the biggest factor is Transport for London being a mostly independent entity - they&#x27;re not required to put money they make back into a central pool, and instead can reinvest it in their own services.
