Stocks of railway companies that transport oil may be in focus this week following the explosion yesterday of a runaway train that was carrying tankers of crude in the Quebec town of Lac-Megantic. The blast, which killed at least one person, left dozens missing and destroyed buildings, is the latest and most serious in a series of accidents involving freight trains, including those of Canadian Pacific (CP) and Berkshire Hathaway's (BRK.A) BNSF. Berkshire's Union Tank Car and Trinity Industries (TRN), which make carriages that hold the oil, may also be exposed, although the accident could strengthen the case for approving TransCanada's (TRP) Keystone oil pipeline.
