SS "Express" was as a tugboat and a passenger tender of the Anchor Line that served on the Clyde from 1880, until her scrapping in 1913.
Construction.
The "Express" was a twin screw tugboat-passenger tender built for the "Anchor Line" in 1880. She was launched in October, and completed just over a month later. She had only one deck with limited passenger accommodation, and a large crane forward to handle cargoes. Her long hull was built out of iron, which was still very commonplace. However, she boasted twin screws, which was a rather unique feature that was soon to become the norm as the evolution of shipping continued to pick up in pace.
Modifications and redundancy.
With the turn of the century on the rise, the "Express" underwent various changes throughout her career. 
As ocean liners grew in size continuously, the old "Express" had been replaced in 1913, and she was sold to the Thomas W. Yard in Preston, Lancashire.
