So, we have Willesden Brent Sidings, Carriage Shed Middle and Carriage Shed North.

I have to say the box looks rather modern, which suggests it replaced the 1965 arrangement. The SBD currently records it dating from 1985. If this is the date of the Wembley changes can anyone supply a precise date, as this is probably the date of the present IFS Unit?

If so, very clever, neater and less labour intensive than carpet! It would seal without being replaced.

Andy Overton wrote:I notice also that your photo of the IFS Unit at North is quite different to that which John suspects might be the IFS Unit in his. So, either it was further replaced or it had gone by the time of John's photo later in the 90s and that box of his is a red-herring.
Andy Overton wrote:John,
Are you absolutely sure that the one in Natalie's photo dates from 1965? That's one of the things I'm getting at, it looks too modern to me and you can see a few NX style push-buttons on it for cancelling alarms or whatnot, and these are of the large, chunky Swisstac type which were not made until the mid-80s. So I rather suspect that it is NOT the 1965 one, that having been replaced in the mid-80s, which would tally with the 1985 date currently in the SBD.
