No cheeky Thomas the Tank Engine, Union Tank Car (UTLX) has important railroad work to do. The company's tank and covered hopper cars haul the bulk goods of corn syrup companies, liquefied petroleum gas (LPG) producers, fertilizer suppliers, and more. UTLX builds, through subsidiary UTLX Manufacturing, and leases tank cars to companies requiring shipping capacities from 13,000 gallons to a whopping 33,000 gallons. Affiliate McKenzie Valve & Machining makes its tank car valves and components. Along with Canadian affiliate Procor Limited, UTLX offers full-service tank car leasing and a network of repair shops throughout North America. A business of Marmon Holdings, UTLX is the equity company's largest operation.
