I'm not sure about boonton coaches, but I believe Bachmann just announced an N-Scale 44-tonner. All things considered, in N scale, I doubt anyone could tell the differences between a late model 44-tonner and a 65-tonner like 112.
On the other hand, MDC has some equipment that could be used as A&A 18 and her train. http://www.blwnscale.com/MDC%202-8-0.htm
The 280 isn't exact, but seems to be the closest in size/shape. If you want better running, but are willing to accept a vastly different engine, a large, high-mounted boiler 2-8-0 is out there. The coaches shown are probably the closest you will find on the market unless you want to see if some DL&W group has had a fleet of brass models made.
