Barclays analyst Brandon Oglenski downgraded Union Pacific (UNP) to Equal Weight from Overweight and lowered his price target for the shares to $170 from $190.

The analyst also cut his Transportation sector view to Neutral saying he sees "real fundamental challenges set against high market expectations." Railroad equities are not properly discounting recent headwinds from softer demand and "lower supply chain urgency" across North America, Oglenski tells investors in a research note.

Further, he sees increasing risk that tariff driven inflation could "damp consumer consumption" later this year, at least in the U.S. As a result, Oglenski suggests investors take some Transportation exposure off the table. He keeps Equal Weight ratings on Canadian National (CNI), Kansas City Southern (KSU) and Norfolk Southern (NSC) as well as Overweight ratings on Canadian Pacific (CP) and CSX (CSX).
