SECOND QUARTER 2026: Monongahela Connecting Railroad supported the operations of Pittsburgh’s Jones & Laughlin Steel from 1885 until the end of operations in 2002. Gordon Lloyd, Jr. covers this Pennsylvania-based industrial railroad’s history and diesel motive power, while Martin Young reviews the development and use of converted diesel locomotives as fuel tenders on the Soo Line. Four former GP20 and GP40 units were converted for this service in 1987, and lasted into the early 2000s.  All this and more in the Second Quarter 2026 issue of Diesel Era!
