CLARENDON HILLS – BNSF Railway Company has notified the village of Clarendon Hills that it will be performing federally mandated upgrades to its signal system from the village of Lisle to the village of Hinsdale.

According to the village of Clarendon Hills, the signal upgrade periods are as follows:
