Talk:British Rail Class 717

Possibly Class 713?
Stumbled across this document: https://www.mobility.siemens.com/mobility/global/SiteCollectionDocuments/en/rail-solutions/commuter-and-regional-trains/desiro-platform/brochure-desiro-city-en.pdf (Page 19)

It suggests that what we know as Class 717 will be called Class 713? I don't know which source is newer, or which one is correct. Superalbs (talk) 16:14, 31 December 2017 (UTC)
