1732: out of service due to broken crankshaft. A replacement engine is in the Thomaston shop, undergoing a slow rebuild.
2203: in service, with some fine-tuning being done. It had some new engine components installed this year (injectors, pumps, governor). Some long-due cosmetic worrk was accomplished at the same time.
2525: stored unserviceable. Has cracked mounting feet on the diesel engine (credit GE's cast iron block vs. EMD and Alco's fabricated steel blocks), due to old impact damage. Replacement block on hand, priority for this work has been low.
529: needs a rebuilt water pump (the one in it now leaks). Also is just about at the limit (but not quite) for wear on some of the wheels. Replacement wheels are on hand, and water pump rebuild is not difficult. Re-wheeling is a considerable project, though. Maybe next season...
1508: this summer, it has been assessed, cleaned up, engine lubed and rotated, cooling system filled and checked for leaks (yes, another water pump to rebuild), air system checked for leaks. Needs a traction motor replaced due to some damage incurred during transit from Michigan.
Like all projects at these places, things move faster when there are more resources* to bring to bear on the projects at hand.
