One of the 8 cars sold to the Rock Island Southern by the Washington Baltimore and Annapolis Electric Railroad in 1910.
The cars were built by Niles in 1907 as 6600VAC cars. They were 62'-3" long, seated 66, and weighed 109,000 # as built. They were part of a group of 19 coaches, all of which had Baldwin 90-40MCB trucks and 4 GE 603 motors. One car was wrecked in 1908, and when the WBandA converted to 1200 VDC in 1910, the cars were sold, with 8 of them going to the Rock Island Southern, becoming #300-305 and #425-426.
The long lingering death of the RIS is documented in CERA's "Smaller Electric Lines of Illinois", and in Hilton and Due.
