European Railway Agency, through EU directives, secured unbundling of maintenance& repair operations from vendors. Vendors no longer are allowed to claim trade secrets or IP as reason for not providing complete and effective maintenance & repair documentation suitable for performing all levels of maintenance.

Since then, MRO is purchased through separate tender process - and NEWAG didn't win several times.

Yeah, the more I look into this the more dire this looks for Newag.

This is a consequence of the train operator winning a court judgement to permit them to use third parties for servicing the trains, followed by "technical measures" of the manufacturer to cripple the trains if this was actually done.

Trains are often, somehow or another, public infrastructure. (In Poland it looks like they are run by state-owned companies, mostly?) Countries should work in the interest of their populations, so really we hope David vs Goliath here, except Goliath is the good guy and also hopefully wins.
