Unit for <tunnel>@crossSection (de: Einheit für <tunnel>@crossSection)
The unit for the cross section of an Tunnel is metre (tLengthM), but must be square metre, as the area of the cross section is meant. Typical values for railways are 80 m² or 100 m², see http://commons.wikimedia.org/wiki/File:4-05m_Tunnelquerschnitt.png for more details.

Proposed solution railML 3.1
railML 3.1 does not implement tunnel cross section.
Proposed solution railML 3.x
When a use case requires the implementation of a tunnel cross section, the resulting model has to consider this issue.
