Edinburgh Street Tramways Co
Works at Shrubhill, Leith Walk
1877 Mr Paterson, secretary to the company, told a Parliamentary committee that the steep gradients made it difficult for the company to use horses. The had tried Perkins's tramway engine, but it did not effectually condense the steam. They had also tried Grantham's, but it was not powerful enough. Merryweather's engine failed for similar reasons. Scott Moncrieff's car was too heavy, and did not carry air enough for their traffic. He had seen Beaumont's air engine at Woolwich, and had a high opinion of it. Mr Hughes's engine had been tried but it was not powerful enough. Large number of vehicles, both carriages and lorries, were being built specially to the gauge in order to work on it. The local authorities were against the use of mechanical power which would only be changed by Parliament.
