See Locobase 13126 for a full account and bibliography of the construction of this railroad. Works numbers were 33217-33218 in February 1909, 33584-33587 in July 1909.
This quartet of Ten-wheelers introduced coal-burning fireboxes to the wheel arrangement on that railway.

Two wood-burning Ten-wheelers delivered in "Exhibition Finish" with engine and tender painted ivy green and gold and the steam chest covers polished. They were tasked with handling curves of 150 metres (492 feet) or about 7 1/2 deg radius (combined with 1 1/2% grades) and maximum grades of 2 % (combined with curves of 200 metres (656 feet) or 5 1/2 deg radius). Rail weight did not exceed 20 kg/metre (40 lb/yard).

A wood burner like the two sisters that preceded her on the production line (Locobase 13292), the 89 was the "flyer". She had more cylinder volume to compensate for the taller drivers. She was also delivered in what Baldwin specified as "Exhibition Finish." This apparently included polished steam chest covers and painting the engine and tender ivy green and gold.
The specs reported that the 89 would negotiate curves of 150 metres (492 feet) or about 7 1/2 deg radius (combined with 1 1/2% grades) and maximum grades of 2 % (combined with curves of 200 metres (656 feet) or 5 1/2 deg radius). Rail weight was 20 kg/metre (40 lb/yard).
