London commuters are making their way into work this morning as the second Tube strike in as many months brings the capital to a standstill.

Members of RMT, TSSA, Aslef and Unite, are striking over negotiations for the implementation of the night Tube from 12 September. Last minute talks on Monday failed to reach a resolution, with union bosses warning that more strikes could be forthcoming ahead of the Night Tube.

Although Londoners have braced themselves for long commutes and packed public transport, early social media activity appears to show the majority of commuters - who rose early - enjoying a relatively easy commute in.

There are 250 extra buses on the roads, with Transport for London Rail services, Overground and the Docklands Railway still working. However, reports indicate that some of these services are already becoming overcrowded.

In July, a similar strike - the largest in over a decade - brought the capital to a virtual standstill as millions of commuters were forced onto the streets as remaining public transport failed to cope.
