Night Moves for Claremont-Concord Alco
On the night of January 30, Claremont- Concord Alco S4 No. 105 was hauled dead-in-tow through the Bridge Street tunnel on Pan Am Railways train BFED (Bellows Falls–East Deerfield), destined for Berkshire Scenic Railway Museum’s new Hoosac Valley Train Ride in North Adams, Mass. The Alco switcher was deemed surplus once Genesee & Wyoming took over the CCRR and merged its operations into the New England Central in 2015.

New Paint Job for Santa Fe 3450
Built in 1927, 4-6-4 3450 was one of 20 Hudsons built by Baldwin for the Santa Fe. Following retirement, it was donated to the Southern California Chapter of the Railway & Locomotive Historical Society in 1955 and placed on display at the Los Angeles County Fairgrounds at Pomona, Calif. The long-awaited boiler asbestos abatement was completed in January. Volunteers will remove the rust on the outside of the boiler, then have a contractor paint the locomotive. The chapter operates the RailGiants Museum at the fairgrounds.

Georgetown Loop Railroad. The engine was moved to Wasatch Railroad Contractors in Cheyenne, Wyo,. at the end of February for repair work under the supervision of Steve Lee, a veteran of the Union Pacific steam program. The South Park Rail Society is expecting the engine to be operating in Como as early as July.
Successful Startup of Rare Maybach Motor is Next Step for SP 9010 Southern Pacific 9010, the sole surviv-
ing 1964-built Krauss-Maffei diesel-hy- draulic road locomotive, has taken a huge leap forward toward regaining its status as a self-propelled locomo- tive. Valentine’s Day found the volun- teer restoration team of the Pacific

Locomotive Association successfully reviving one of the German-American hybrid’s Maybach Mercedes-Benz V-16 turbomotors, asleep for 48 years. SP 9010 was built with a pair of four-cycle, 16-cylinder V-type diesel motors, delivering an astounding 4,000 h.p. in a six-axle single-unit locomo- tive. It’s a figure common in 2017 but unparalleled at the time. Designed for high output and low weight, each motor has a stiff tunnel-type crankcase with a roller bearing web crankshaft, oil-cooled two-part pistons, six valves per cylinder, dual overhead camshafts, unit fuel injectors, and two exhaust gas turbochargers mounted on vertical axes in the 60-degree cylinder valley. Each motor has twin charge air intercoolers, a compression ratio of 16.2:1, and is rated at 2,000 h.p. at 1,600 r.p.m.
In Fall 1968, SP 9010’s forward Maybach suffered catastrophic cylinder damage, prematurely retiring the unit. Its hydraulic powertrain was immobi- lized when the unit was pulled from the scrapline and converted to a non-pow- ered training simulator camera car. Preparations to reactivate the engine
began in 2010 with a careful assess- ment of the undamaged rear motor by PLA’s Howard P. Wise and a small crew of dedicated volunteers. Some serious lubrication and muscle power allowed volunteers to bar the engine loose from its decades-long nap. Over the next six years, Wise and his crew prepared the unit for a test start. The motor was tested under pressure with its lube, fuel, and cooling circuits; rebuilt injectors were installed and meticulously timed, and the resilient rubber coupling to the
