The station opened with 4 platforms served by 3 tracks similar to Canary Wharf, and was accessed via an underpass[7].

As the DLR was expanded eastwards the station was remodelled with a new overbridge, the island platforms narrowed to serve 4 rather than 3 tracks, and extended to take two-car operation.

On 28 March 1994 Poplar became the western terminus of the new Beckton branch, which opened the same day; on 31 July 1995, the line was extended west, joining Poplar with Westferry via a flying junction and enabling Beckton services to run to Tower Gateway.

It will also provide a platform for schools and groups to showcase art and it is hoped the scheme will make travelling through the station a more pleasant experience.

[10] As part of the construction of the Elizabeth line, Canary Wharf railway station was built and opened in 2022.
