"remains about armpit height"

Travel Laurie Penny is leaving London. Here she is romancing the underground:

"More than anything, I wanted the tube. Every time we went to London for a visit, I could happily have ridden the underground all day. I wanted to lose myself in the dark and mouse-running scramble of crammed-together humanity and come up again in the light. I liked being one of the sardine people, even in rush hour, even at my height, which was and remains about armpit height on the average commuter. Late at night, the platforms echo with the memory of thousands of city dwellers huddled together for shelter with the bombs of the Blitz overhead. Catching the last Bakerloo line home, you can almost see them, out of the corner of your eye, through the cracks in history: propped against one another, mindlessly tired."

Yes, absolutely. Merseyrail just isn't the same.
