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)

Class maximum speed

Danners230 (talk · contribs) it seems that you take an issue with the maximum speed being updated. I am not referring to the line speed or any speed specified on the DMI at 2:10 in the video in https://www.networkrailmediacentre.co.uk/news/east-coast-digital-milestone-signals-a-new-era. That sticker stating 'Cab B max. speed 100 mph' above the driver's head to the left displays the maximum speed of the train, which is lower than some speed limits on the ECML south of Welwyn (I can find track speed limits of up to 115 mph, and the ECML can go up to 125 mph in places, such as Stevenage). This is a normal feature in modern multiple units to clearly and unambiguously indicate the maximum speed that train can go to the driver. Please stop reverting this change. ~2026-44489-63 (talk) 14:09, 2 October 2026 (UTC)

That sounds a lot like original research to me. We need a proper citation to support any change. Thanks. 10mmsocket (talk) 14:32, 2 October 2026 (UTC)

It's such common knowledge among those familiar with a driving cab that it's easier to explain by showing counter-examples than by trying to find a sufficiently reputable source. It would be absolutely ridiculous to say that that sticker regulates what speed a train can go at all times, or that the train is segregated to one 'line' that it can go at any speed under that number over any track no matter the radius or cant. It is merely the absolute maximum speed that that train can travel, subject to the permanent speed restrictions on the tracks (the lowest applicable value of the permanent, temporary, and train speed limits is what the train is driven to).

If however there is objection to the use of Network Rail as a 'proper citation' then there are many citations from less reputable industry sources, which are known for their unreliability, which should be removed. If anything is the definition of original information it is that, given that Network Rail do not own, operate, lease, or otherwise control the trains. They merely control the infrastructure that it runs on (as well as all of the rest of the national rail network).

Just find a citation it's that simple 10mmsocket (talk) 17:13, 2 October 2026 (UTC)

So easy. --Redrose64 🌹 (talk) 21:53, 2 October 2026 (UTC)
