HBL introduces new line of Flame Retardant Batteries for passenger rail vehicles

HBL has been requested by several railways and railway OEM’s to develop a range of batteries with transparent, flame retardant battery cases for metro and light rail applications. This required HBL to develop entirely new molding tools and techniques – as well as fully testing the products to the clients demanding standards. HBL delivered on time and on budget – the first of these batteries are now entering service in Boston with the Massachusetts Bay Transportation Authority.
