With regards to the matter of Whifflet, queries were made some years ago on this quiz, with its currently open station and the number of former stations in that town area, which caused a special mention of Rule 4 shown above, which is covered by the comments expressed in that particular rule.
Whifflet has had stations of the following railways:-
Garnkirk and Glasgow Railway
Monkland and Kirkintilloch Railway
Caledonian Railway...this had Whifflet Lower (closed 1962) and Whifflet Upper (closed 1964)
There were two lines that were used in the area, that led to different junction connections further down both lines.
