June 2004 and No.1 has no touble traversing the intact 'Mt Lyell' bridge... in December 2007 the same journey may be a little more difficult... The bridge collapsed when the rushing water built up a wall of debris against it, the force of the water finally broke the bridge and pushed it out from under the track. Most of the 'bits' have been recovered from under the swimming pool, but I think it will be rebuilt in a more substancial form. The embankment leading around to Underpool station (inset) was also washed away.
