A few weeks ago train NE-97 was rolling through Empire City when the lead engine, Erie Lackawanna F7A suffered catastrophic engine failure. The engine was shut down and brought into the New York Central Train Layout Terminal Yard Shop for evaluation and possible repair.
The F7A in question is a Bachmann Plus unit bought when they were first released about 15 years ago. This is a straight DC 8 wheel drive dual fly wheel equipped engine. It had been a good rugged engine for it's entire service life until this motor failure. So what to do? A common question among modelers who operate aging fleets. Options include repowering, converting to non powered free rolling "dummy" unit, putting it on a display shelf, putting it back in the box and forgetting about it, etc.
The N.Y.C.T.L. Purchasing Department was contacted and approved the purchase of three new Bachmann motors directly from Bachmann. I believe they had a 20% off coupon burning a hole in their collective pockets. The purchasing agent checked the in stock availability of replacement motors and found F7A motor# 8812A deemed to be the 6172 replacement motor and an actual 6172 motor listed under the H16-44 parts section.
The original 6172 type was chosen and the parts arrived within a week. Follow along as the N.Y.C.T.L. Shop gets down to business.
