Has anyone here built Eastern Car Works heavyweight passenger cars? If so, would you tell me about them? Specifically: Do they come with interiors? Will the versions with 4-wheel trucks handle 22-24 inch curves? How's the level of detail? How much time do they require to assemble? I'm looking for some generic coaches for commuter service on a free-lanced branch of CNJ. I considered IHC heavyweights but by the time I change to 4-wheel trucks, add interiors, and repaint I'm in the same price range as ECW, so if they're good models I'd be inclined to go that way.
