And LGW, BHX both directly linked to terminals, the latter is on the West Coast Mainline one of the most important in the UK. I think Stansted has an airport too.
I was being flippant, apologies.
The above are good examples of joined up planning, LGW dates from the 1960s and STN from the late 1980s.
Remember that LCY did not have the DLR until it had been open for a good many years, I remember it being built in the mid 2000s, NOT being plugged into public transport held LCY back for years.
