Train Headache
SNCF, a French train company, learned the hard way that it’s impossible to fit wide trains onto narrow railways. Unfortunately, by the time they learned this lesson, they had already bought 2,000 trains for $20 billion. Then they discovered that the trains were too wide to fit into most of the train stations the company needed them to travel to. So, SNCF had no other choice but to spend an extra $68 million to widen the train platforms so that the trains they spent billions on would fit.
