Good points of view and reviews.
PS The Berkshire manual on page 15 also provides incorrect volume control directions. Correct: Hold down the cab chat/shift button while turning the throttle knob to desired volume. Not the bell and whistle buttons at the same time for 3 seconds or more. All that did for me was simultaneously sound the whiste and bell. Learned this from watching an AF Berkshire YouTube video kindly posted by a train club. Or, of course, use the LionChief app which I think is terrific with the additional functions and adjustments that you can access with it.
Lionel can get it right on some occasions. If you purchased the Frisco 4-8-4 Meteor Northern the included manual gives the correct directions to adjust the volume using the remote on page 11. Those same instructions will apply for the Geeps and Baldwins:
