Did you miss "Mad Money" on CNBC? If so, here are some of Jim Cramer's top takeaways.

When an old-school, large-cap company sees its shares double in less than a year, it's time to sit up and take notice, Cramer told viewers. That's been the story at railroad CSX (CSX) shares of which have rallied from $25 to $53, and already are up over 50% for the year.

Cramer said much of CSX's gains stem from one thing: its long-time CEO Michael Ward stepping down last month and being replaced by Hunter Harrison, the former CEO of Canadian Pacific (CP) .

Harrison is a proponent of what's known as precision schedule railroading, the running of fewer, smaller trains on tighter schedules with tighter cost controls. Even though precision scheduling is fairly new at CSX, the company is already seeing 14% improvements in velocity and a 52% rise in on-time arrivals.

Cramer said that CSX is an earnings story, plain and simple, and the company just posted a 38% rise in earnings per share and has a $1 billion buyback and a nice dividend to boot.
