Deleted Shelby & Rachel Glee Fanfic

I'm looking for the fanfiction Runaway Train by stockette. I want to say it was published around 2014. It was about Rachel running away in New York and meeting Shelby. I think there was also something with Cassie Shelby worked as a dance teacher at a studio that she owned with Cassie. I don't remember much else, but I know that was the title and I'm pretty sure that was the author. It was one of my favorites and I would be forever grateful if someone had it so I could read it again. It was only ever posted on ffn.net. I can't find it on AO3
