ATP systems include a check on air pressure to ensure that there is sufficient air available to brake the train. There was an accident recently in Taiwan where an ATP equipped tilting train derailed while overspeeding on a curve. The ATP had been disabled as low air pressure resulted in frequent emergency brake applications. 3 Link to post Share on other sites More sharing options...

On fixed consist trains it is automatic. Not sure for others but logically automatic as it is safety critical. But I am still unsure where you found the terminology. 1 Link to post Share on other sites More sharing options...
Shed Posted May 27, 2020 Share Posted May 27, 2020 seen on a list for required on board data I would assume that this would all be specific to the train and thus stored in the EVC and not have to entered manually by the driver? 1 Link to post Share on other sites More sharing options...

It does seem odd that a "first in class" 387 is considered necessary when a fleet fitment already exists, and that it is implied that the same design is replicable on all the other Electrostar classes. Most of the earlier ones have quite significant differences from the 387, not least having been built before future provision for ETCS became mandatory. I can only think the "first in class" is related to the issues that might arise during DC operation, or that they've got the class number wrong and they should be referring to a 375. 1 1 Link to post Share on other sites More sharing options...

For starters, NO units are fitted with ERTMS, they are fitted with the on-board elements of ETCS. Off the top of my head: Class 158 - TfW Cambrian Units only Class 195 Class 196 Class 221** Class 313 - Okay, only one unit Class 331 Class 345 Class 374 - I presume they have ETCS fitted and use it via a STM? Class 390** Class 397 Class 387/1A Class 700 Class 701* Class 707 Class 710 Class 717 Class 720 Class 730 Class 745 Class 755 Class 800* Class 801* Class 802* The ones in bold are units that have it fitted and are using it in an ETCS Level. The ones with * are ones that are using the Packet 44 element of the ETCS Data for ASDO / APCO / ISDD / ABDO systems. The ones with ** have an EVC to read the Packet 44 TASS Data for Tilting, but don't have the full ETCS DMI. The rest have it fitted (I believe as they are all new build units, although I'm happy to corrected) and the ETCS DMI is used to provide the speedometer etc (expect for the GWR Class 80x's as they use the ATP Speedometer).

RMweb Premium iands Posted May 22, 2021 RMweb Premium Share Posted May 22, 2021 To provide some clarification (and not in any way criticism), essentially ERTMS has major four elements; GSM-R (the communications element) ETCS (the signalling element) Traffic Management System (not yet fully developed) and the Standard Operating Rules The units/locos etc., will obviously be fitted with the "mobile" equipment of the first three elements listed above. 1 Link to post Share on other sites More sharing options...

ess1uk Posted June 8, 2021 Share Posted June 8, 2021 The Northern City Line Project is progressing well with on site teams who are fully mobilised installing equipment in a difficult environment working within two tunnel bores. REB and Tunnel Locs are built and ready to be installed over the next 2 months across multiple disruptives, with the first major disruptive starting on 19th June 2021.

I know what it's like down there, I used to do 3-monthly (in theory, in practice could be as little as once a year) cab rides on the 313s checking the CSR coverage. Also the routes between KX to Cambridge and Peterborough. 2 Link to post Share on other sites More sharing options...

Heard on the grapevine that KX North will be version 2.3.0 as per Thameslink but NCL will be done first (i.e. before KX North), so about 2025 for KX North to go live. Then all to be "uprevved" to version 3.6. Not sure if the proposed "big bang overnight change" for ECML will still happen, or if an overlay option will be introduced initially - still a long way to go yet. 2 Link to post Share on other sites More sharing options...
