And about the line in general, does anyone know much about the history of this line? Apparently one of the reasons it was closed was due to frequent flood damage.
A brief history of the line apperaed in the Westland about 15 years ago.
The line was on its last legs by the time of the 82 floods. The Asplin bridges had been damaged in the Alby floods of early 78 and the repair work took many months. Trains from Kattanning terminated at Asplin and trains from Picton terminated at Boyup Brook. When the bridges were reopened there was a vibe that the line would not last. At the time Westrail was purging itself of uneconomic class 5 lines, (ie with 11 ton axle loading) either by upgrading or closing. them. Boyup Brook -Kattanning was a class 5 line and, the cream of other traffic having gone to subsidised road competition, the only way that a case could have been made to the pollies at the line was to demonstate that there was sufficent grain and super traffic moving along the line. Had Bunbury remained open as a grain port the three bins at Boyup, Qualeup and Kojonup could probably have shipped enough grain to justify keeping the line open, however, when the decision was made to close Bunbury it effectively killed the line east of Boyup. The line becam seseasonal in 1981, and had it not been for the 82 floods it may have lingered another year or two. Unfortuntely, the 82 floods damaged the formation between Muradup and Kojonup (as I recall) which provided the excuse to close it. A tour to Muradup was mooted using the LLRPS rolling stock but canned when Westrail refused to guarantee the safety of the train, which is not surprising. The perway was so bad during the last years of the lines life that derailments were not uncommon, including a bingle when the track gave up trying to cope with the dynamics of two gyarating rigid base Crossleys.
