Fountain: Limehouse Station drinking fountain
Erection date: 1885
Gift of St. George's Tufnell Park, Band of Mercy.
The inscription which is on marble is barely legible, so we are grateful Wikipedia for the information.
One has to wonder why a group associated with Tufnell Park, 5 or 6 miles away, is giving a drinking fountain to Limehouse Station.
2018: via Facebook Olly Houlton answered our query by providing this link to the MDFCTA which says that the fountain was originally installed in 1885 in York Road (presumably York Way) near the then cattle market. Removed by Islington Council in 1902 due to "misuse" by children it was re-erected here in 1906 by the MDFCTA in what was then Stepney railway station.
