It was a while ago now but when I was coming off a D stock at Wimbledon and I noticed a guards panel in the cab. I thought that was very odd considering that fact that the District is now all OPO.
Did the D78 ever operate with guards?
A final thing, if the D stock have a guards panel, could the operate on the IOW IF they are clear for running through Ryde tunnel?

D Stock certainly operated with Guards from introduction on 28 January 1980 until OPO on 4 November 1985. They could easily revert to crew mode as a locking-bar simply connects the Control and Position switch barrel, everything still works on the Guards panel, for drivers use, except the button marked 'signal'. D Stock (and indeed all Surface Stock) would be unable to use Ryde tunnel as it stands. |

I remember D78s coming into service and I'm fairly sure that they had guards to start with. If they altered Ryde tunnel I don't see why not although that would mean they could choose other standard commuter stock as well, LUL or otherwise. EDIT: Apologies to DStock above, he can type faster than me obviously!  |

Yes, they did operate with guards at the start of their careers, before transitioning to OPO. The guard panel is still used (albeit it's probably better described as a rear wall door panel) when doing things like selective close. If they were cleared through the ryde tunnel, and were modified to run off of the 3rd rail system used there, then they could run - although they might have a task getting hold of some from Vivarail, especially following yesterdays announcement, which may well have made it a bit more likely that D-Train will go ahead,

. If they were cleared through the ryde tunnel, , There is nothing about ex-LT surface stock which would make it more suitable for the IoW than, say, a 313, if the clearances in Ryde Tunnel were improved to allow normal sized stock through . And simply improving the clearances would be relatively easy - just lower the floor to the original level. But that is to ignore the reason the floor was raised in the first place - to get the live rail above the level to which it tends to flood. So, you can have full sized stock, or electric stock, through that tunnel - but not both. If it's electric it has to be tube sized. If its full size it can't be electric. So no, D stock could only work on the IOW if it were one of Vivarail's conversions (and even then the amount of gear they intend to put under the floor would make it very unwise unless it was very well waterproofed). A diesel hydraulic with above-floor engine would be better. |

Vehicle length is as much if not more an issue for the reverse-curved Ryde Tunnel as height (apparently some of the overbridges around Ryde remained the greatest restraints on height even after the track level was raised) and would be much more difficult to address - this makes the typically shorter LU designs better suited to the Island than 20m+ long mainline designs. It seems the unusually short/low Merseyrail 503s were considered, and believed to in-gauge, for this reason - a photo of testing with a mock-up can be seen here |
