The track through Pontoon Dock parallels the ( A1020 ) North Woolwich Road , and gives excellent views to the south across the Thames Barrier Park of the Thames Barrier . Pontoon Dock station is near the small eponymous quay , the Barrier Point residential complex and Royal Wharf , a large commercial and residential development on the riverside , which now covers the location previously owned by Brunner Mond , where the infamous Silvertown explosion occurred and where there is now a small memorial . As of September 2016 , this memorial has been moved to the main park of the Royal Wharf development . A crossover at Pontoon Dock allows trains to reverse in service disruptions
