Chillagoe Railway &amp; Mining Co.
After a number of proposals had been made for the route of a railway to the Etheridge field, construction of the Etheridge Railway finally commenced in 1906 from Almaden to Mount Surprise on the Mareeba to Chillagoe line. The railway was opened to Mount Surprise in May 1908, and through to Einasleigh on 8 February 1909, a total of 101 miles. The final 41 miles from Einasleigh to Forsayth were not opened until 5 February 1911, construction having proceeded slowly due to union unrest and uncertainty within the mining industry generally.
Etheridge railway line
Around 1917 a lime burning business started at Ootann, south of Almaden, using old kilns used during the construction of the railway, and a siding was installed about 1918. Ootann was the limit of steam operation from 1927 to 1951. It had a shelter shed by 1935, and an overhead gantry for loading lime. The present main line was originally the siding, as the main line was moved to install the gantry. Gelaro at had a crossing loop, levers and a shelter shed by 1969. Bullock Creek at had a siding and railway phone by 1916, and was the site of a permanent fettler's (rail line maintenance worker's) camp by 1932. There was a side loading bank and shelter by 1935, and private cattle yards by 1951. A water tank was present, although this no longer exists. The loading of cattle at Bullock Creek ceased in late 1991.
