The Eastern Car Company produced its first boxcar for the Grand Trunk Railway in August 1913, with GTR #105000 being the first of a 2,000 car order. SCOTIA also established the Dominion Wheel Foundry in 1913 on an adjacent site to Eastern Car Company and the steel mill and forge operation. Dominion Wheel Foundry created cast iron railway wheels in support of its sister operation at the Eastern Car Company. Finally, 1913 also saw SCOTIA establish a bolt and rivet factory to the entire complex.
