Decade after decade, the Roundhouse played a critical role in Barrie's economy by servicing transcontinental passenger train travel in all directions from the Allandale Train Station. Railway steam locomotives were moved from the main line to the Roundhouse for repairs. Since the huge engines ran backward so slowly, the engineering genius of a roundhouse was that locomotives weighing several tons could be easily rotated on a turntable of tracks and moved forward into stalls for maintenance and storage.

Flaming Disaster
Imagine being called out on a freezing early morning in January to fight a mass of flames at the old Northern Railway roundhouse. It was 1887 and the Allandale Fire Brigade and the Barrie Fire Brigade together could not save the 1870s roundhouse, with its carloads of wood and three locomotives inside. Incredibly, the newly built roundhouse burned again the following year in July. The rail yard could not function without a roundhouse, so yet another roundhouse had to be built.

Solid Concrete
Work started in 1903 and, this time, the Grand Trunk Railway chose to use the newly available building material of poured concrete.

It took many men to build the new roundhouse which could service up to 27 steam locomotives at

a time. The 21.3m (70 foot) turntable in the centre was operated by air motor tractor. A Foreman's office, tool room, air brake testing department and accommodations for the electricians was also added.

Demolition
The introduction of diesel engines, plus the decline of rail traffic through Allandale, resulted in the roundhouse closing in October 1958. The building was demolished in 1964, leaving only the concrete footprint in memory of its working days.

(by Deb Exel, 3/3/2024)  Excerpt:  Thanks to a fixed tax assessment in 1903 for all its Barrie properties, the Grand Trunk Railway began a significant expansion of the Allandale rail yards. Master Mechanic’s and Stores, a poured-concrete building, was erected for office staff and a parts department. Next to the Master Mechanic’s building, work commenced on the building of a roundhouse. Roundhouses

were designed to service steam locomotives. As early steam engines could only move in one direction, most roundhouses also had a turntable nearby to swing the locomotive around or manoeuvre them into the bays of the roundhouse, which radiated around the turntable.
Reporting of the day stated the diameter of the roundhouse would be 332 feet and its foundation was five feet below the rails and two feet wide. Above ground, the 20-foot walls would be 13 inches thick. More than 16,000 bags of cement would be used to build the enormous structure. It was estimated about 50 men were contracted to build the roundhouse, with additional teams hired to grade and level the entire yard to bring it to the height of the rails in the roundhouse. The roundhouse would have 28 stalls measuring 20 by 80 feet each. In the centre of the massive roundhouse would be a 70-foot air-operated turntable.

As a remembrance of the great monument of railroad history that once stood on these station lands, a round, concrete band to represent the walls of the former roundhouse was placed in the plaza of the park.
