We all know that the MBTA needs a little TLC when those famous New England winters come around—especially after the apocalyptic winter we had last year.
But what about in the hot, muggy days of summer? Even without the hurdles of snow and ice, riders might be surprised to learn that the warmer seasons bring their own unique challenges to America’s oldest subway system.
Winter’s extreme cold can snap rails. In summer, high temperatures can cause a potentially dangerous condition known as “spaghetti rail,” spokesperson Jason Johnson explained.
Only it’s not nearly as delicious as it sounds.
“[Just] as extreme cold may cause rail to contract and pull apart at the joints—or completely break—extreme heat may cause the opposite, with expansion causing the rail to grow and, in some cases, resulting with a kink,” Johnson said.
