Hey all, how ya'll are? Gotta question on a part on the Atlas N scale locos. What do they call the piece that wraps around the entire frame that has the footplating, handrail holes, and steps? I want to order some, but since see.... Oops! Just remembered to look at the "Instructions" They call it a SILL UNIT. Thanks for the help anyways. SOOO... How Is everyone? Myself: Father had a heart attack on Sunday morning. Monday morning mom had a VERY mild stroke worrying about dad. So now dad's out (with a very strict diet and orders to workout more), and mom's in awaiting word on her MRI's.
