TheStreet's Action Alerts PLUS Portfolio Manager Jim Cramer said Canadian Pacific (CP - Get Report)  could make a bid for another railroad, after abandoning its plan to merge with Norfolk Southern (NSC - Get Report) , but the antitrust environment out there makes it difficult for any railroad mergers to be approved by regulators. The government recently nixed Pfizer's (PFE - Get Report)  $160 billion merger with Allegan (ACT) .
