In 1925, the Lima 2-8-4 demonstrator A-1 completed test service on the B&A, and the Boston & Maine chose to try her as well.  They received their initial order of 20 locomotives in 1928, and an additional five locomotives (Class T1b) in 1929.  All 25 locomotives were equipped with a notable Coffin feedwater heater extending forward from the smokebox, and trailing trucks with boosters.  The most noticeable difference between the T1a and T1b locomotives is the shape and size of the large sand dome in the center of the boiler, and we have also modeled several less visible differences in conduit and piping.  Another major difference is that the T1a's ran with a 4-wheel tender for much of their lives, whereas the T1b's ran with a 6-wheel tender from the beginning.  Our models of the T1a have a 4-wheel tender, our  models of the T1b have a 6-wheel tender. 

In our first production, we are offering models of four fully decorated T1a's and two decorated T1b's, along with an unlettered model of each.  Each of the models will come with a disk main driver and Baker valve gear.  Our models have die cast locomotive and tender bodies for maximum weight and tractive effort.  Each model comes with our Paragon4 Sound/DC/DCC sound system with synchronized puffing smoke and integral GoPack capacitors.
