Good news everyone!
As you might have read on the MNG steam team work session reports, we have been given permission to use steam locomotive #4 on a limited basis for the remainder of the year. She had her first steam up 22 months on the 10th and ran back and forth on the engine house lead a few times before being put away.
#4 is tentatively scheduled (and subject to change without notice) to run the final 2 weekends of October (22/23 and 29/30) for shakedowns (for both engine and crew). #4 will also be the primary power for the Polar Express.
Again, I stress that this is subject to #4 not experiencing any issues in operation.
