Thursday, April 24th, Hi Group, I have Several of the Micro Trains Center Beam Cars. (18 so Far) Great Cars Except I Have Some Issues, Just Wondering If Others have Had the Issues I"ve Come Across. 1) I Keep My Cars in the Cases When NOT in Use. I've Noticed the End Pieces are Coming Loose or Off After a While. Its NOT Because I Rough Handled the Cars Either. For Now I'm Using Testers Glue to Glue Them Back On. If They are Good Cars They Should NOT B Having Assembly Quality Issues Under Ideal Conditions. I Haven't Said Anything to Micro Trains - Yet but am Wondering If Its Wise to Tell Them They Have a Quality Control Issue on the Cars. 2) I've Taken 3 Cars and Took the Trucks Off to Replace the Plastic Wheels With Metal Wheels to See How Well They Run. Problem I CAN"T Get the Truck Pins Back Into the Holes - Same Truck Pins etc. Any Solutions???. Looked at Taking a a Tiny Screw Driver and Hammer and Hammering Them Back into Metal Bottoms, Doesn't Work so My Next Option is to Redrill the Holes and Hope for the Best, or Just Send the Cars Back to Micro Trains and Ask Them to Re Assemble the Cars and Mail Them Back. I've Never Had Issues With Micro Train Cars/Trucks and Have Changed Out Trucks With No Problems Till Now. Anyone Else had Issues With Center Beam Bottoms and Trucks. Just Wondering. Thanks Group, Operator.
