RMweb Gold PaulRhB Posted October 10, 2014 RMweb Gold Share Posted October 10, 2014 Sandite mostly run as class 3 though they used to use class 8, might still depend on the region. Some areas are water jet only. Sandite is good for traction but in certain areas the likelyhood of it causing trains to disappear means you have to block work the following train as a safety measure. So if not required it may be left off, things that require sandite would be stations with crossings near them, or junctions in known adhesion problem areas. Each train runs a certain circuit so if they've said there's no adhesion risk only wrong side track clear risk that set may be booked for that. The MPV's and RHTT's can lay both or each individually with a tick sheet issued to the operator sitting alongside the driver to say which is required. We also sometimes will contact them to request slower speed passes without sandite, or adhesion modifier as it's now known, to clean contaminated railhead. There are extra restrictions in for Signalboxes where equipment is activated by track circuits and barriers next to platforms are locked on Non Stop selection during the Leaf Fall period in case of overshoots. Add that to the extra trains and it can get quite busy even on a good day At Salisbury we have two MPV circuits plus a RHTT off the Western. Day circuits only at the moment, this week and next, then they add the night circuits too. Sandite or Adhesion Modifier is a paste including sand and metal particles for contact through the sand formulated to stick around on the railhead. It's also used in static machines at certain places with treadles operated by the train pumping it into the rail. Makes a real mess if you stack it in unrestrained piles in a van too as one of my colleagues found out when he opened the rear doors Link to post Share on other sites More sharing options...

I think all the RHTT's are class 3 - The sandite trains are 3Sxx and the water jet only 3Jxx Here's a link to the RHTT workings, but don't know if you have to be a member of wnxx to access it (EDIT - you do have to be signed up to wnxx to access it - sorry!)

RMweb Gold PaulRhB Posted October 10, 2014 RMweb Gold Share Posted October 10, 2014 I just knew though Mick if I said they were no longer any class 8 there'd be one circuit left somewhere! Not at work so couldn't check on TRUST. Link to post Share on other sites More sharing options...

Cheers, Mick In previous years some WCML workings have been Class 1 due to the need for the signallers to make sure they give them the path (ie not treat them as freight), and I believe they were cleared for faster speeds along those sections also?

RMweb Gold PaulRhB Posted October 10, 2014 RMweb Gold Share Posted October 10, 2014 You can run the trains faster but it limits the effectiveness as they're designed to operate best at 40. It's 80% effective at 60 if memory serves so we do sometimes run them faster where time needs to be clawed back but not on bad days Control can respond to reports of problems by modifying the circuit during the run too if needed via the Signalboxes.

RMweb Gold beast66606 Posted October 11, 2014 RMweb Gold Share Posted October 11, 2014 The use of class 2 is not confined to passenger trains The Anglia area ones must be starting very soon as the paths are now in the system for the maintenance moves - Stowmarket - Norwich and return - commencining Monday.

RMweb Gold PaulRhB Posted October 11, 2014 RMweb Gold Share Posted October 11, 2014 Class codes are really about priority and speed rather than cast in stone for type. You would consider a 1,2 or 9 as passenger unless you have a notice otherwise and that tells you it can't go on goods lines unless the notice says so, as with an mpv or charter. 1z99 is the standard headcode for a rescue train whether it's empty units or a loco. If it's an in service passenger it keeps it's own code if rescuing another. Link to post Share on other sites More sharing options...
AberdeenBill Posted October 11, 2014 Share Posted October 11, 2014 Hi all, According to realtimetrains, there's some interesting RHTT action tomorrow in the north of Scotland. We start with a 10:00am from Inverness, passing Dyce at 14:07 and proceeding to Dundee (reverse) and getting back to Dyce at 19:06 Meanwhile, 3S95 leaves Inverness at 15:30 and gets to Dyce at 18:49. Then, if I understand correctly, they combine (depart Dyce 19:19) and return to Inverness, arriving at 23:31 Any idea what the motive power will be? Just for good measure, the diverted Inverness to Euston sleeper passes Dyce at 22:00. Thanks, Bill Link to post Share on other sites More sharing options...

AberdeenBill Posted October 12, 2014 Share Posted October 12, 2014 Hi all, The 10:00am ex Inverness was cancelled today, but 3S95 made it to Dyce, where 67007 ran around (picture below) and returned from where it came... I'm sure I'm the only person not to know this, but why does 67007 have white numbers at one end? Thanks, Bill Link to post Share on other sites More sharing options...
RMweb Gold Metr0Land Posted October 12, 2014 RMweb Gold Share Posted October 12, 2014 I've no idea. 67.007 had them in at least April 2004 and seems to have carried them ever since. Link to post Share on other sites More sharing options...
