While I was browsing the rolling stock pages of Tubeprune's site, I started to think about the length of time the "A" stock had been in service, and what a great tribute to the stock it is to be still performing today.
On his site Tubeprune says that there were 56.5 trains built, what I am wondering is are all of these units still in operation today? or have some been scrapped for spares or due to accident damage.

There is of course a conversion to the TRT straight off. Poor Cravens though: they lost series production 1960 Stock orders and apart from DMUs what other railway stock did they produce in any serious production?

The table on my site refers to the number in the current fleet. There were originally 31 A60 Stock and 27 A62 Stock trains. The losses are due to collision damage and some resulting reformation over the years. |

It seems that Cravens of Sheffield folded in 1964, but the LM11 Class 311 electrics debuted in 1967 according to Wiki, which does not make sense!

I can't see that there is any more to add, TP is spot on. Delivery of the A60's began in 1961 and continued until late 1962.

There is always more to add! Jazza, TP is correct, there have been some reformations due to collision damage. In 1981 there was a dreadful accident at Kilburn where unit 5028-29 hit unit 5116-5117. The surviving cars 5/6028 and 5/6117 became double ended unit 5232-5233. In addition, traffic levels on the Met never rose to the expectations of LU so there was always an excess of A stock (hence their deployment on the ELL). Because of this, unit 5036-37 was cannibalised for spares (trailer 6036 became a sandite car in 1985) and a few other cars were put into storage after suffering minor depot 'knocks'. Eventually these trains were repaired and later refurbished to cover for the A stock refurbishment.
Although stated in some texts that there are only 24 double ended units, there are, in fact 26-with the two extra units being made up of spare cars.
Finally out of the starting number of cars, 11 cars have been scrapped, 5 between 1981-7 and 6 in 1994.

I'm sure I heard that the reason the order was so large was to cover any future extension of electric services to Aylesbury if it ever became an option.

I know they were thinking of discontinuing the Chiltern service to Marylebone (and selling the land) and there were plans to extend electrification to Great Missenden and maybe Wendover.

Yes, you are correct. Thinking about it, the reason so many A60/62 trains were delivered was for service improvements! Remember when the A stock was ordered, Rickmansworth was the limit of electrification and there were still (just about) 2 tracks between Harrow North Junction and Watford South Junction. I guess the planners forcast a huge rise in passenger demand which just didn't happen! The single doors D/83t stock was the result of falling passenger numbers.
The A60 stock was designed to replace the (10?) Steam Dreadnought and (16)T Stock trains and the A62 the (8) F stock and (14.5) O/P stock (sent to the District Line).
1960s peak train frequencies on the main line were far more than todays!
