Comment As the electric services were designed to draw power from a raised conductor rail outside the track, they were not considered safe enough for street running, so the sections in Portrush (from the town's station to the depot) and Bushmills (the branch line to the Market Place) were steam operated. In actual fact, and due to delays in finishing the power station, the entire service was steam operated for around the first six months of the line's life.
Numerous photographs showing staff of the Giant's Causeway Tramway have survived, and these clearly show that uniforms were worn (see link); marked buttons have, however, not come to light, suggesting that the buttons were either plain, or that they bore a monogram or device that is not readily identifiable as an issue of the company.
