Łódz Cross-City is having problems since day one.  I wrote before: Completion of the railway tunnel under Łódź is now officially by a year. Original completion date was December 2021. but was delayed to "sometime in" in 2022 with no specific quarter information.

Expect more delays. Now it is announced the smaller Herrenknecht TBM will start to bore in January 2021. Previous announcement had said it start in December 2020. There is no delay announced for completion. For now I think.
