Very local to me, and in my area,
Following on from the darker side of the line between Birmingham Snow Hiill and Worcester, now for the Southern side,
We have the other side of the line, between Birmingham Snow Hill and Stratford upon Avon via Shirley known as the North Warwickshire line, although we like to call it and plus the local train crews, that work it, nickname it further, the North Warwicks, nicknamed further.
Even more diverse the older generation, and other generations of Train Crew, ie Charter and Vintage trains, nickname it the Shakespeare Line after William Shakespeares birthplace in Stratford upon Avon, and the Shakespeare Express itself,
This Line is unique in having 3 nicknames,
Plus 4 nicknames including the darker side as mentioned above, involving the direct services from Stratford upon Avon to Worcester that operate on it,
