Line 623: :The central service tunnel is used with double-ended electric/diesel rubber-tyred vehicles. These are electrically guided, but are road-based, not trains. As far as "rescue trains" akin to the Swiss LRZ NT (Fire Fighting and Rescue Train)—there aren't any par-se for the Channel Tunnel. Stock used for rescue efforts have included Class 373 EMUs, Passenger Shuttle rakes and Eurotunnel's various locomotives. I don't recall having heard of Class 92 locomotives being used in the situations thus far, but these would might be situation aswell. —[[User:Sladen|Sladen]] ([[User talk:Sladen|talk]]) 04:39, 22 December 2009 (UTC) == Channel tunnel freight == *''copied from [[User talk:Sladen#Channel tunnel freight]] at request[http://en.wikipedia.org/w/index.php?title=User_talk%3ASladen&action=historysubmit&diff=333368190&oldid=333367241] of [[User:Shortfatlad]]'' As I understand it the article is about the channel tunnel, not eurotunnels operations - other freight operators eg DB Schenker or Euro Cargo Rail do operate freight trains through the channel tunnel (without using class 92s). If this is somehow wrong of me please mention it on the talk page.[[User:Shortfatlad|Shortfatlad]] ([[User talk:Shortfatlad|talk]]) 19:40, 22 December 2009 (UTC) :The only electric locomotives currently allowed (and suitably equipped) to traverse the [[Channel Tunnel]] under their own power are the [[Eurotunnel Class 9]], [[British Rail Class 373]] Power Car and [[British Rail Class 92]] locomotive. Before the final delivery of the Class 92s, nine [[SNCF Class BB 22200]] locos ''were'' temporally used; and in addition, two [[British Rail Class 319]] also made a pair of (one-off) return VIP trips through in 1993. :You can't just send any old locomotive through the Chunnel; the '''catenary''' is higher than normal (because of clearances for the RO-RO Shuttle wagons), the train requires TVM430 cab compatible '''signalling''' (with an even more special Eurotunnel parameter set), Eurotunnel network-compatible '''radio''' (trunked UHF), special post-derailment '''lifting points'''; then all of the ''extra'' requirements laid down by the Inter-Governmental Commission ('''fire''' suppression, dual '''redundancy'''—basically two locomotives in one bodyshell). :All of these requirements are laid down in the publicly available Eurotunnel Network Statement[http://www.eurotunnel.com/NR/rdonlyres/02B57D98-A0DF-49D8-9010-7F75A4D76F9D/0/DRR_NS_2009_EN_Final2.pdf]; the necessary sections are 4.1.4 (signalling), 4.2.1 (Class 92) and Appendix 2 ("Technical Specifications Concerning the Rolling Stock"). :[http://www.inrets.fr/ur/splott/Seminaire-EMAR/diaporamas/diapoEurotunnel.pdf] (page 15) notes that the "through the tunnel" sections are hauled by Class 92s [only]. Were there any further queries you had? —[[User:Sladen|Sladen]] ([[User talk:Sladen#top|talk]]) 20:27, 22 December 2009 (UTC) ::Thanks, but can you use the articles talk page for the feedback - it may help others.
