ÖBB’s 15 kV frequency

The text of the Railroad Gazette article: Brenner base tunnel approved

"Power supply will be at 25 kV 50 Hz, with changeover from ÖBB’s 15 kV 167 Hz in approach tunnels at each end."

appears to have omitted a period thereby creating "167Hz" instead of the probably intended "16.7Hz" as cited at Austrian Federal Railways. SBaker43 (talk) 06:11, 24 October 2010 (UTC)

Brenner Base Tunnel reached the construction phase

The Brenner-base-tunnel has past its planned phase and is now in the construction phase. This is since the final go ahead sign was given in Innsbruck on April 18th, 2011. EU coordinator Pat Cox spoke in German language that day "With this step we have reached the point of no return. The coming of the Brenner Base Tunnel is definitive and the main construction phase of the 55 km long base-tunnel has already started. --145.53.144.81 (talk) 16:33, 6 April 2012 (UTC)

Second longest tunnel in the world

It actually will be the longest tunnel in the world, as the Innsbruck_bypass together with the BBT accumulates to some 64 km of continuous tunnel. BBT Basic data

Why is the tunnel not flat?

Ok, this is more a personal curiosity, but it could also be added to the page: why does the tunnel have to climb up and have an apex? Why couldn't they just make it flat? I googled around a bit, but found no answer. Nasopanic (talk) 17:54, 27 March 2024 (UTC)

Innsbruck is at a height of 600 m above sea level, Franzensfeste at 750 m, so an entirely "flat" tunnel wasn't an option anyway. Additionally, a major concern for any tunnel of this length is dealing with potential water ingress, so having an incline will help avoiding a situation where the tunnel is partially flooded. And since Austria and Italy wanted to make sure, that water remains on their respective national territories, the apex was built exactly at the border. Mai-Sachme (talk) 08:03, 28 March 2024 (UTC)

Thank you for the clear explanation :) Nasopanic (talk) 11:51, 28 March 2024 (UTC)
