T413 was running a special passenger train to Shelley when it derailed in Tallangatta yard. As far as I am aware, this ceased tours, and indeed it is unlikely any other train ran beyond Tallangatta (excepting rail recovery). 
In this photo, the flat wagons for the poles deposited earlier in the week by the special goods (see the mail for 20.5.1979), can also be seen in the yard. Their later removal may have been the last train on the branch.
