The 20 minute interval service needs 3 trains to make it happen - only running 2 trains will give alternating 20 minute and 40 minute service intervals. BR knew this - yet it still removed the double track between Brading and Sandown to cut costs when the 1938 stock was bought over! They disguised it by saying that the double track / ability to pass trains at Brading was 'not needed' as a 20minute interval service would be offered - and it was for a year or two until further financial cuts were demanded and the stock started to become unreliable. With the ability to pass at Brading no longer an option the timetable was thus forced into the uneven 20 / 40 minute pattern we have seen for the past two decades. Would Brading be a passing place for a 3 train service? Or would trains for that only cross at Sandown and on the double track section in Ryde? 1 Link to post Share on other sites More sharing options...

The Brading passing loop is only needed for a 30 minute service using 2 trains crossing there As was described earlier, if a 3 train service is operated then trains will cross at Sandown and on the double track section at Ryde. This gives a 20minute interval service. If, as has been the case for around a decade, there are only 2 trains in operation and passing can only be done at Sandown and in Ryde that will give an uneven 20 / 40 minute service - which is why the passing loop at Brading is being installed to even it out. 2 1 Link to post Share on other sites More sharing options...

BR knew this - yet it still removed the double track between Brading and Sandown to cut costs when the 1938 stock was bought over! If I remember correctly, one of the main reasons for removing the up line between Brading and Sandown was due to slippage of the embankment on Morton Common, near the A 3055 road bridge. This may have been a legacy from when this section was doubled and additional material was tipped on the upside to widen the formation. 2 3 Link to post Share on other sites More sharing options...
roythebus1 Posted April 12, 2021 Share Posted April 12, 2021 a lot of the redundant rail from the lifted double track was used by the IWSR for the extension from Hvenstreet to Smallbrook, as was a lot of rail from the Alton-Farnham line. I'm one of the few IWSR members who can claim to have driven an electric train on those rails at 70mph! 5 Link to post Share on other sites More sharing options...
Christopher125 Posted April 20, 2021 Share Posted April 20, 2021 (edited) These facebook posts show progress at Sandown and Shanklin (the split-level platform and miles of fencing look.... interesting), and Smallbrook. Note the missing Up signal alongside the headshunt. https://www.facebook.com/groups/355569249197459/permalink/478321476922235/ https://www.facebook.com/groups/355569249197459/permalink/478111670276549/ All the new signals at Brading are now up, though only one has route indicators curiously. Ramps down to the foot crossing are underway and copers back on the Down platform.

Presumably the southbound one? So that trains towards Shanklin can use the platform with direct access to the street if it's not passing another train. Though I'm kind of surprised they haven't gone with sprung points like at Sandown, it's a rather marginal benefit really. 1 Link to post Share on other sites More sharing options...

NR dislikes sprung points - too much chance of the switch rail / stretcher bars breaking due to fatigue as trains repeatedly push it over which creates a derailment risk. Again the spectre of Grayrig has a lot to answer for.... Those that already exist can stay but no more will be installed on passenger lines. Given the railway is shut I'm surprised that there hasn't been more done in the way of a signal upgrade - particularly making the two passing loops (Sandown as well as the new Brading one) the same, 1 Link to post Share on other sites More sharing options...
Zomboid Posted April 21, 2021 Share Posted April 21, 2021 Fair enough, though I wonder what the risk actually is on a route like the IOW, where more of a light railway approach might be appropriate. There's not much more similarities between the IOW railway and the WCML than the track gauge. But I have no idea what was considered and ruled out. 1 Link to post Share on other sites More sharing options...

Does anyone know why there are two sets of route indicator lights on this signal? I'm sure in the past there would only have been one, which would normally have applied to the diverging route.

I don't know for sure, in this case, but such use of feathers has been used in other locations, where both routes are of the same speed limit. Very rare, but they do exist. The sole example I can recall was on the entrance to the platforms at Margate, where the route dissected on a curve and both tracks were 45 mph restriction. Either that, or there is a distinct chance of the Bembridge branch re-opening?? 1 Link to post Share on other sites More sharing options...
RMweb Premium John M Upton Posted April 27, 2021 RMweb Premium Share Posted April 27, 2021 Various news reports surfacing this afternoon that the reopening has been delayed still further until at least late Summer, maybe even December. Software issues with the new stock apparently. 1 Link to post Share on other sites More sharing options...
KeithHC Posted April 27, 2021 Share Posted April 27, 2021 There’s a news item in railway gazette. There are issues with use on 3rd rail it means there will be testing at Eastleigh before the units are moved to the island. Keith 1 Link to post Share on other sites More sharing options...
RMweb Premium Chris116 Posted April 27, 2021 RMweb Premium Share Posted April 27, 2021 The news of the delay does not bode well for the late evening boat to Portsmouth being reinstated. That in turn spoils my day of Isle of Wight Steam Railway followed by Speedway at Smallbrook Stadium and home to Wimbledon on the last boat/train. I was hoping to be able to do that trip on 8th July as the Speedway includes Sidecars which on the big track on the island should be very entertaining. I may have to change my plans somewhat. 1 Link to post Share on other sites More sharing options...

Also it will adversely affect both the steam railway and the Speedway promotion which after the problems they have faced over the last year is something they can do without.

Just remind me again, what powered said trains when they were on London Underground? Oh yes, electricity from a live rail! And I am pretty sure they didn't have software, probably not so much as a pocket calculator when they were originally built.

But surely they’ve been substantially rebuilt since then, so that may not be relevant. Presumably the third rail issues are new because they are not relevant for the 230s, though how much software is actually in a D-train? 2 Link to post Share on other sites More sharing options...

RMweb Premium John M Upton Posted April 28, 2021 RMweb Premium Share Posted April 28, 2021 I doubt Sarah Siddons would fit through Ryde Tunnel but the possibility is intriguing. Does the Island Line have mainland safety systems, e.g. AWS and TPWS? 1 Link to post Share on other sites More sharing options...
