Armor might be renamed to suggest, like, business-wear, or ppe, the kind of thing that technically follows the rules but is pointless. Modular armor and up might suggest the idea that you are taking your own safety and productivity into your own hands, with personal equipment specifically requiring paperwork explaining them as business expenses.
Also energy shields should be explained as a high visibility or reflective vest, suggesting that trains are able to not run you over when they can see you.
