New late night service planned for Lewisham DLR

TfL's plan for light railway growth, which incorporates two new trains per hour on the ELL, also proposes late night services on the DLR, from 2021. They say:

Night services on DLR are planned for 2021 after the Bank station upgrade works are complete, and the current franchise and City Greenwich Lewisham Railway Lewisham route contract have ended. 

Night services are planned to operate from Bank to Lewisham and Bank to Canning Town/Woolwich with a four trains per hour service operating on each route. In early 2015, frequency doubled in the late evenings on Bank-Lewisham and off peak on the Woolwich route.

The document notes that, as with the ELL, this area is a major driver in the growing demand for rail journeys. It says:

Seven stations have contributed 50 per cent of DLR’s growth over the last four years. These are Woolwich Arsenal, Stratford, Bank, Canning Town, Shadwell, Heron Quays and Lewisham... Growth has been strong on the Stratford-Canary Wharf/Lewisham route.
