This page contains train pressure data for the following Southbound train runs:

Train Run Number Speed (km/h) Data File
35338 163.5 35338-z001-p.dat
35340 202.0 35340-z004-p.dat

35358 198 35358-z008-p.dat

The data files can be viewed in a text editor and can be downloaded from http://www.thermotun.com/airshaft/train/train-pressure-southbound-dat.zip

Notes about these measurements have been included on the train pressure data page.

Example Graphs

The following example graphs have been produced from data file 35340-z004-p.dat.

For both directions of travel, the pressure histories include passage through two tunnels. One is Emmerquerung Tunnel. The other is a short tunnel further south. In the southbound run 35340 the train enters the two tunnels at approximately 533s and 570s.
