I repainted a Legacy S-2 into the half-ballon paint scheme over the winter. The half-baloon scheme was applied to engines from about 1950 - 1953, and refers to the quarter circle of green where the bottom hood stripe meets the cab - the full-ballon paint scheme that succeded this has a full half circle between the top and bottom hood stripes. 0610 continued in this paint scheme until the Penn Central merger.
I also added a whistle, as can be seen on the engineers side of the engine by the cab overhang. All New Haven Alco S-1's and S-2's had steam locomotive whistles instead of horns. Since I took these photos I have also added the cab signaling box on the engineers side walkway.
