 The new trams for the Lochee route were supplied with EMB swing-axle trucks, manufactured by the Electro-Mechanical Brake Company of West Bromwich, which gave a much smoother ride, and caused less wear of the track.This type of truck was fitted to the trams as they were rebuilt, while other improvements included air brakes and Fischer bow collectors, which increased the contact area between the overhead wire and the collector, reducing both wear and noise.There were several sizes of rebuilt trams, but the largest, which ran on four-wheel trucks, were designed with seating for 68 passengers.
