For those of you who like to slice and dice so as to make unusual streetcar projects, here is an example of prototypical kitbashing. In 1916, the Connecticut Company took two old single-truck cars with 18' bodies and spliced them together to make a 49' long, center-entrance car. The original curved sides were shimmed out to allow straight sheathing below the windows. It was narrow, but had longitudinal bench seats so probably not an issue. Numbered 1605, the experimental car was intended for rush hour service in New Haven, but was transferred to Waterbury because the steps were too low for New Haven curbs. Although the procedure was apparently not repeated, Car 1605 ran for many years before being scrapped in 1929. Get out your Dremels!
The article in ELECTRIC RAILWAY JOURNAL describing this car appeared in the November 18, 1916 issue, pages 1069-1070.
