hexagon789 Posted October 19, 2022 Share Posted October 19, 2022 Locomotive Services Limited revealed their latest railtour set, a homage to the ScotRail Express push-pull sets of the 1980s. DBSO 9707 and a set of five Mk3s have been repainted in ScotRail Express livery to go with Crewe Heritage Diesel's 47712 Lady Diana Spencer: https://m.facebook.com/story.php?story_fbid=pfbid026ytHFDgkQR9ByNtyEz3jJE4b4fU8mT8pT3PNx5cwdtgbicu5LnZffgYrTWEeSRofl&id=100075707029121&eav=AfYcMzvrUQy2FT6XMYHnu8VbvUqS-Lj8iGPgqzejw_4tKpdq4lgNC3uyctxeIP5MxXs&m_entstream_source=timeline&paipv=0 16 1 Link to post Share on other sites More sharing options...

I understand the plan is for test runs later this year, with a view to the first passenger carrying tour in January. 47712 was recently given overhauled bogies and R5 blocks to permit 95mph specially.

RMweb Gold Bucoops Posted October 19, 2022 RMweb Gold Share Posted October 19, 2022 I do have a huge softspot for the DBSOs having hitched many a ride out of Liverpool St so this is wonderful. 1 Link to post Share on other sites More sharing options...
luckymucklebackit Posted October 20, 2022 Share Posted October 20, 2022 Well, we still have some class 27s that worked the push-pulls next project?.......... 3 Link to post Share on other sites More sharing options...
RMweb Premium newbryford Posted February 9, 2023 RMweb Premium Share Posted February 9, 2023 47712 has been out and about on test with LSL's push pull set. Flickr pics Not using the original TDM control, but the Class 47 MU connector - you can see the jumper plugged in just above the buffer beam. Which makes perfect sense if 712 was to suffer a failure, other LSL47s can be used. 11 Link to post Share on other sites More sharing options...
RMweb Gold 4630 Posted February 9, 2023 RMweb Gold Share Posted February 9, 2023 That really does look very smart. Well done LSL. Link to post Share on other sites More sharing options...
Waverley West Posted February 9, 2023 Share Posted February 9, 2023 Now there's a fine sight I'd thought I'd never see again. What a fantastic job. Well done to everyone involved! Just need a CO tucked in behind the DBSO and the FOs dressed up as SOs (some people are never happy). 1 Link to post Share on other sites More sharing options...

The DBSO was already converted by DRS to use this in conjunction with 37s and Blue Star is one of the more widely used systems. 47712 plus two other 47s have been modified to use Blue Star and the Mk3 coaches have had a through control air pipe fitted. 1 2 Link to post Share on other sites More sharing options...

It's also easier to use with older locos which use control air throttles as well, you may as well simply use air to control engine speed from a driving trailer than fit an electronic system to transmit control inputs which then has to interface to something which then sets a control air pressure for the engine control itself. The one draw back is lag, at least the sets are short but you need to make sure the control pipe is fairly leak free otherwise the control air pressure gets low and it takes an absolute age to transmit a throttle speed increase. 1 Link to post Share on other sites More sharing options...

Presumably the 'lag' is on applying power and the brakes are still controlled instantly from the DBSO? Link to post Share on other sites More sharing options...
RMweb Premium newbryford Posted February 9, 2023 RMweb Premium Share Posted February 9, 2023 There is a possibility that a model set will be running on Deadmans Lane ate Glasgow in two weeks. Courtesy of a friend. There's a few details still to be sorted. 6 2 1 Link to post Share on other sites More sharing options...

Yes, standard brake controller identical to that in a 47 - and using the UIC twin-pipe automatic air brake system. 1 Link to post Share on other sites More sharing options...

And this of course harks back to the system used by the p-p cl.27s i.e only so-fitted coaches could be used. The cl.47/7 system was a Glasgow Works home-made solution which was developed into the TDM system, advantage being any coaches with RCH/lighting jumpers could be placed in a set. There are some test-run videos on YouTube. e.g. Is it just me or is the dark upper panel black, instead of Executive/Intercity dark grey?

I understood that was jointly developed by BR and Brush and initially at least there were plans to utilise additional BSOs with modified 81s/85s on the Great Eastern Main Line to Norwich, some 10 years before push-pull was actually introduced there. 15 minutes ago, keefer said: Is it just me or is the dark upper panel black, instead of Executive/Intercity dark grey? It looks a bit dark I agree, but LSL do usually make the effort to get the correct colour specs. When I've seen her with my own eyes as opposed to through the camera lens, I'll give you my verdict on that! 1 1 Link to post Share on other sites More sharing options...

RMweb Gold rodent279 Posted February 11, 2023 RMweb Gold Share Posted February 11, 2023 The DBSO doesn't appear to have a cow catcher. I thought that was a requirement for a DBSO after Polmont? Link to post Share on other sites More sharing options...

The obstacle deflector is still there, I think it's the fresh paint makes it blend in more - perhaps this photo from ALAN HART shows it better: (ALAN HART Flickr) 2 1 Link to post Share on other sites More sharing options...
