ART Railway grade enclosures can be either for static or dynamic applications, the latter often requiring very special design requirements. Static enclosures can be track-side or within substations. Dynamic enclosures are specific to rolling stock applications and can be either mounted underframe or internally within the carriage. Underframe enclosure features include Robust construction to withstand routine shock and vibration loads, ballast or other missile strikes and vandalism, High levels of corrosion protection to withstand extreme temperatures and humidity’s, salt-laden air, acidic train wash solutions, so that mechanical attachments are not compromised so that critical contents continue to function normally. This is achieved by primarily using stainless steel, or careful painting processes. Special attention to door/panel seals is required to maintain ingress protection levels. Internal enclosures features include Compact packaging, Ease of service, Special attention to materials to ensure low flammability and toxicity in the event of fire.
