This Prairie saddle tank joined the two others from 1909-1910 described in Locobase 13569. Duplicating all the principal dimensions, the 10 weighed 2 1/2 short tons (2.27 metric tons) more.
In 1957, the Grand Falls Central bought the lines of the Anglo-Newfoundland Development Corporation between Windsor, Grand Falls, Bishop's Falls and Botwood. The 10 was scrapped in 1958.

Compared to the two that would follow (Locobase 13569), this saddle-tank Prairie was quite a bit bigger. Was it too big?

The pair of saddle tanks in this order joined smaller tanks like the 2 (Locobase 13570) in serving the newsprint shuttle between Grand Falls and the port of Botwoodville.
