VLookup To Output Text Data Results?

I have a column with lots of tube station names. I have a look up table with the tube station name, and the possible lines that pass by that tube station.

One tube station may be covered by more than one tube line.

I am looking for a formula that will output every tube line that caters that one tube station.

first question, what is the best way to organise the data in my look up table.
Second, is a vlookup the best formula to achieve the output I want? i.e. Reflect how many tube lines cover each station

see table below: If the station name has only one tube line, Vlookup works fine. When the station, such as Canno Street, has two tube lines, Vlookup only picks up one tube line. If I duplicate Cannot street under the station name, the Vlookup picks only one tube line.

LOOK UP TABLE A1 - station name
B1 Tube line name
Cannon Street
District

[Code].....

Is there a formula that will output the data of the second tube line name in column D1?
