RMweb Premium DRS Crewe On A Mission Posted December 20, 2014 RMweb Premium Share Posted December 20, 2014 Surely that cannot be how they are meant to work. As they are LED maybe they would go off if not needed but the flickering is very strange considering only the bottom two do it and the top one doesn't.

'CHARD Posted December 20, 2014 Share Posted December 20, 2014 If you notice, LED P.I.S displays on rolling stock and buses all flicker too. It's not visible to the naked eye, or I guess our brain processes it as a constant light source. The camera does pick it up though, as it refreshes the image at a rate which intercepts the minuscule gaps in the emitted light. The destination displays on both of these would have been visible to you or eye, but not the camera at the moment the image was captured: http://wmbusphotos.com/NXWM/4700-4879/4919.html http://wmbusphotos.com/NXWM/4700-4879/4929.html Link to post Share on other sites More sharing options...
RMweb Premium DRS Crewe On A Mission Posted December 20, 2014 RMweb Premium Share Posted December 20, 2014 Hmm interesting yes maybe we do LED lights as a light which is constantly on in some cases. The lights flickering on the 68 though look really obvious especially when the top one doesn't look like its flickering at all. Link to post Share on other sites More sharing options...

As they are LED maybe they would go off if not needed but the flickering is very strange considering only the bottom two do it and the top one doesn't. The top one is a different light unit, its only a marker light. It seem to be when the headlights are on full or dipped beam.

RMweb Premium DRS Crewe On A Mission Posted December 20, 2014 RMweb Premium Share Posted December 20, 2014 This one has left me a little confused. Might sound stupid but I wonder if the drivers of the 68s know about the lights flickering on the front. Do the lights flicker when the 68 is stationary I wonder?

BR(S) Posted December 20, 2014 Share Posted December 20, 2014 Just to be clear on this, the lights don't flicker on the real thing if looked at with the eye (i.e. there isn't a fault with the lights). They only seem to be flickering because of the way the camera picks up LED lighting. Link to post Share on other sites More sharing options...
RMweb Premium DRS Crewe On A Mission Posted December 20, 2014 RMweb Premium Share Posted December 20, 2014 Just watched a video of 68011 on the 6U77 and the lights didn't flicker on the loco. Must be the type of device that your using to record the loco that determines if the lights flicker or not then. Thanks for clearing that one up.

You can't tell the lights are flickering when driving them, its the type of camera that picks up this phenomenon, not all devices pick it up Link to post Share on other sites More sharing options...

robkellett Posted December 22, 2014 Share Posted December 22, 2014 It was pathed as a Class 158 DMU, but still 1 hour 13 minutes: http://www.realtimetrains.co.uk/train/P52323/2014/12/15/advanced Sorry! My fault. i meant 23 minutes to High Wycombe. Rob K Link to post Share on other sites More sharing options...
BR(S) Posted December 22, 2014 Share Posted December 22, 2014 Similar effect in this video of the camera on lights, but this time with the signal. Definitely not an East Coast flashing green as it happens to the red as well!

RMweb Premium jamie92208 Posted January 6, 2015 RMweb Premium Share Posted January 6, 2015 Has anyone got any update on how many services are 68 hauled at the moment. I'm heading down to leamington and banbury this Thursday and was wondering how many I was likely to see. Are they mainly on the Marylebone to Moor Street Services which are shown as 100 mph Class 158 paths on Real Time Trains. Any help would be appreciated.

Iron Horse Posted January 6, 2015 Share Posted January 6, 2015 They are the ones in the National Rail timetable 115 shown as having a Business Zone if that helps? Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted January 6, 2015 RMweb Gold Share Posted January 6, 2015 The "'banbury" set is mk3s and loco but isn't shown as having business class as its a peak hour standard class set. The 68s were parked up at Wembley the couple of times I travelled that way over the xmas period. They are having problems with them on the Business sets but are apparently OK on the Banbury set.

Bulleidnutter Posted January 6, 2015 Share Posted January 6, 2015 Came past Wembley yesterday morning on the 1045. 2 x 68s and 3 67s in the depot along with the spare blue and grey set and one other all silver set. Link to post Share on other sites More sharing options...
robkellett Posted January 7, 2015 Share Posted January 7, 2015 Came past Wembley yesterday morning on the 1045. 2 x 68s and 3 67s in the depot along with the spare blue and grey set and one other all silver set. This morning (8am) 68010 was stabled in the loop between the shed and washer, 67008 & 20 were stabled in the siding at the east end and 68012 was coupled to the blue / grey (Banbury) mk3s. Presumably for a training run. This means that todays Banbury mk3 commuter ran as a dmu! Additional note. When I arrived at Marylebone this evening for the 17:50 to Banbury I was pleased to see 68012 in charge. Fast acceleration and arrival in High Wycombe in 22 minutes.

RMweb Premium jamie92208 Posted January 8, 2015 RMweb Premium Share Posted January 8, 2015 No sign of any 68's at Banbury today between 12.05 and 15.41. Three 67's (14, 10 plus one other) were seen on trains to/from Marylebone. Jamie Link to post Share on other sites More sharing options...

St. Simon Posted January 8, 2015 Share Posted January 8, 2015 Something to do with doors, or are they not controlled from the loco at all? Hi, I doubt that the doors are controlled from the Loco, this would mean that installation of an extra set of controls just for these locos, which I wouldn't think that DBS would be willing to do for what is a pretty small operation and fleet I can't recall exactly what it was when I was told but it's certainly to do with the wiring Could be something to with Push pull and Door signals interfering with each other?

Christopher125 Posted January 9, 2015 Share Posted January 9, 2015 Could be something to with Push pull and Door signals interfering with each other? Simon IIRC it was suggested on another forum that they have issues with the MAs on Chilterns refurbed Mk3s, presumably they don't like the power supply from the 68s?
