Under the agreement, a CME3 shunting locomotive will be rebuilt by CZ Loko at an LDZ workshop using fuel cells supplied by Ballard Power Systems. CZ Loko will be responsible for design work on the project and will also provide components for the rebuild.

LDZ and CZ Loko have previously worked together on a number of locomotive modernisation projects, including the rebuilding of CME3 and 2M62 locomotives.
