Digitrax retires their DCS51 Zephyr All-in-one Command Station/Booster/Throttle and replaces it with DCS52 Zephyr Express: All-in-one Command Station/Booster/Throttle with different display and buttons.
Someone needs to pay attention when updatng their web site - they used the template from Challenger to do the retired product page for the Zephyr Xtra - it says “replaced by Big Boy” and takes you to the Big Boy system retired product page, saying it was repalced by the Empire Builder, etc… oops.
But for a whole $10 more you get the computer interface built in and a color LCD, bargain for sure.
