Tunnel Pressure Data - Southbound

This page contains pressure data measured in the tunnel during the following Southbound train runs:

Train Run Number Speed (km/h) Data File
35334 157.5 35334-t16b-p.dat
35338 163.5 35338-t18a-p.dat
35340 202.0 35340-t19a-p.dat
35352 202.0 35352-t21b-p.dat
35358 198 35358-t22b-p.dat
35362 197.5 35362-t23b-p.dat

Each data file contains records from two separate pressure transducers positioned in the same location. The data files can be opened in a text editor. All of the above data files can be downloaded from http://www.ThermoTun/airshaft/tunnel/tunnel-southbound_dat.zip
