Kevin,
I had three sheds and the station on my previous Flyer layout. Lionel re-did them a few years ago and I had to get three of them. They also advertised them for O gauge by using the two pedestrian platforms to raise the whole shed for O gauge clearance, but it may not be necessary. I got some for my O gauge buddy and he loves them along with two original Gilbert stations I restored for him before their reintroduction. There's plenty of clearance for S, not so much with O if you don't raise the sheds with the platforms. On my layout I didn't use the pedestrian platforms since I had three tracks under the sheds.
They're still out there, both as original Gilbert items and the Lionel releases.
