Rail Road LEDs

We are trying to use the BR631-0CW-028M 28V-BP TM in a Railway application, powered via a multipair cable. The problem we discovered is that in the cable we have pairs caring either 110VAC 60Hz or|and 600VAC 4Hz. Connecting the BR631 to a pair of wires in the cable, the LED will flicker at the 600VAC EMI and light steady, dimmed at the 110VAC. We are looking to have an EMI shield or installation scheme to eliminate this EMI. Can you help?
