E400 Bus Route Dubai: The Twin-Emirate Express from Union Square to Ajman

 

Dear All, here are the details about the E400 Bus Route Dubai | The E400 is one of Dubai’s most established twin-emirate links, connecting Union Square Bus Station with Ajman’s Al Musallah Bus Station day and night.

E400 Bus Route Dubai runs alongside its sister service, the E411, as one of two RTA routes covering the Dubai-Ajman corridor. Departing from Union Square Bus Station, it passes Safeer Mall, Crown Palace Hotel, Grand Mart, and Al Manama Mall before reaching its Ajman terminus – a genuinely well-used route for the many people who live in Ajman and commute into Dubai daily, or vice versa.

Compared to the E411, the E400 makes more stops along its roughly 29 km route, so if speed matters more than coverage, it’s worth checking both options on the S’hail app before choosing. Reported fares for this route are also unusually inconsistent between sources, so confirm the current price before you travel, especially if it matters which direction you’re heading.
