On our January 2007 Austrian epic, photographer Denis McCabe and I drove a hired car up a hill at Penk in the Alps to score this view of a massive arched bridge on the Tauern Pass.

Traffic over the route is light compared with either the Brenner or Semmering alpine routes. Yet, we caught several trains in a relatively short span of time.

Here, an ÖBB Siemens Taurus electric leads an Intercity passenger bound for Villach in southern Austria.

The scale of the bridge seems out of proportion with the railway; its like an O-scale structure carrying an N-scale train.
