Canadian Pacific Railway (CP - Get Report) dropped its bid to hook up with Norfolk Southern (NSC - Get Report) last month, but that does not mean Norfolk's shares are unattractive, said Mark DeVaul, portfolio manager for the Hennessy Equity and Income Fund (HEIFX - Get Report) . 'There is a high barrier to entry in the railroad business,' said DeVaul. 'And while coal has been a drag on profits in recent years, the negative impact is limited.' The Hennessy Equity and Income Fund has returned 1.4 percent thus far in 2016, according to Morningstar.
