Newbie here. A few months ago I located in my attic a thirty year old Bachmann train set my son enjoyed for years to now enjoy with my grandsons. Deciding to expand the collection I just bought the Overland Limited train set which includes one of the 4 8 4 locomotive versions. I openly admit I have no clue about the front and rear "floating' 4 wheel sets that will not remain on the rails. What am I missing? What am I doing wrong? Please advise. I am confident that this question makes me look like an idiot but I am clueless and can't keep the locomotive on the track. Help is greatly appreciated.
