Took a slightly used k-27. I plan on running it on at least 6ft minimum radius track. Counter weights appears to be tight. I know earlier Bachmann locos like the connie had trouble with gears. I think the k-27 has metal just geared a bit to fast.
Anything other than good periodic lubrication to kerp it running.
Hi Chastity,
Talked to my son yesterday, his K 27 continues to run just fine, no issues with the gears. He does lube regularly.

Thanks
