The railway through Triberg climbs the hill opposite the waterfalls we covered yesterday, to get out of the Gutach valley and proceed to Villingen. But inclines are notoriously difficult for trains, as metal-on-metal contact yields little friction, so, like many other modes of transport, whether roads or even footpaths, the railway weaves its way up... but on a larger scale, as trains aren't as maneuverable!

The result is this loopy section between Hornberg and Sommerau, 11 km apart in a straight line, but the railway is 26 km long! It climbs 447 m at an average gradient of 1.7% (which, again, for a train, is hard work), and with over 30 tunnels to get through the irregular terrain. Today, an "Adventure Trail" complements the route opposite Triberg, providing hikers with amazing viewpoints and some chances to get close to the tracks.

Of course, this climb for hikers is far, far steeper! The route I took started with a strenuous 15% over 700 m. One would be very happy to find this bench after that climb - Liegewagen meaning "sleeper car"!

The trail has stations with information boards about various aspects of the railway, and, at the viewpoints, the timetable! Perhaps a bit of a downer is that there isn't a huge amount of traffic: just two DB Regio trains per hour (presumably the ones you came in on), one InterCity train at weekends, no high-speed ICEs, no freight. But the views more than make up for the low variety, and, at a decent pace, it is possible to be at a viewpoint for each passage and not miss one.

Most regional trains on this section of the Schwarzwaldbahn are push-pull sets with Dosto carriages - that's short for Doppelstockwagen, or double-deck. The end carriage seen above is a (deep breath)... DBpbzfa 766, each letter being short for some technical info allowing rail workers to know at a glance what they're dealing with: D is for double-deck, B second-class seating, p has air conditioned coach rooms (as opposed to compartments), b has wheelchair accessibility, z has a centralised electrical installation, f has a driving cab, and finally a means that the driver can operate the doors alone. 766 is the series number. These Dosto sets are usually driven by Baureihe 146 locomotives.

All in all, the Erlebnispfad can take up most of an afternoon (I completed the circuit in around 3 hours), it was a very satisfying walk and experience to be able to make the most of each vantage point. There are some other attractions along the route that I haven't mentioned - probably a short post tomorrow. For people who like hiking and trains, this trail at Triberg is worth doing!
