Snowpiercer Melanie Cavill (Played By Jennifer Connelly) Screen Worn Jumpsuit W/Belt & Lace-Up Boots Ep 201-202

With Layton taking over the train, Melanie, as played by Jennifer Connelly, relaxes her look and wears her engineering outfit instead of the hospitality uniform. She wore the components of this wardrobe set in episodes 201 and 202, before she ventures to the research station. Most notably, she was wearing these when she went to the engine of Big Alice, where Wilford instructs Alex to disconnect Snowpiercer, which fails due to a bomb Melanie had planted in the mechanism.
