This is not a complaint, but a note of caution. After an hour of runtime, my H-10 "Pennsylvania Lines" sound began to crackle and pop. No other sounds could be heard. The noise did not stop until I turned off the ZW-L transformer. (Shut down sequence did not work.) When I turned the transformer back on, the engine operated normally and the noise was gone. (I may need a YLB electronic battery if space in the tender allows.)
I noticed the left handrail on the top of the Lines West Tender had moved backward over the red tender deck by over 1/2" while running. The railing had not been glued in place by the factory.
These observations are for your assistance. Check detail parts to make sure the factory secured them in place.
I like the H-10 "Pennsylvania Lines" steam engine and hope tonight's sound glitch is not indicative of other sound issues. I ordered the #1773 H-10 Coal Hauler Set today before tonight's experience. The H-10 steam engine is my best purchase in 2018. This and my three Pennsylvania B6 Switchers are great little engines.
Sincerely, John Rowlen
