The formality would allow management to "examine and prepare a sale of up to 100% of the shares in Schenker," the internal documents state ahead of a supervisory board meeting next week.

This gives the state-backed train company the opportunity to consider a complete or partial sale to Schenker's competitors or to financial investors.

An IPO would also be possible, although this is currently considered unlikely in the volatile market enviroment.

A spokesperson for Deutsche Bahn declined to comment.
