Hello, here is my suggestion. It is for the City Widened Lines between Moorgate and ECML. This line was closed, mostly, in 2009 to complete the Thameslink project's aim to have 12 car trains down under London. My suggestion would see a line in the 1970s where the line was run by class 31s and class 23s (Baby Deltics),and weird suburban mk1 coaches that were non-corridor and shorter to fit around the tight Hotel and York road curves, as well as class 105 DMUs The stations would be: Moorgate: Barbican: Kings Cross (Metropolitan): Kings Cross (York Road): Kings Cross (Hotel Curve): I hope this is to most people's liking and any help would be greatly apricated.

No, as this is the Northern City Line that joins the ECML at Finsbury Park. The City Widened Lines joined at Kings Cross, and later St. Pancras/Kentish Town. Here is the Wikipedia link: https://en.wikipedia.org/wiki/Widened_Lines Thanks for your help.
