First of all I must point out that I know next to nothing in this field but here is most certainly the place to find out.
I was wondering whether if we ever want to see stocks which have only had one car preserved running again, would it be possible to run two different kinds of stock back to back? I know that 1972 mk1 stock certainly could work with 1967 stock and I’ve even heard of 1962 stock operating with 1992 stock and so, could we at some point in the future see an A stock DM running again if it were attached to a C stock DM? There’s probably reasons as to why this hasn’t happened already, but it’s been bugging me for ages and so i thought i’d ask.
Many thanks, Oliver

Many thanks, Oliver It’s a nice idea, but unfortunately it’s almost certainly not feasible. The first major problem which springs to mind is you need compressors, which are generally located on a trailer car. Without compressors there is no supply of air, which means the train can’t run. The second issue is that the circuits are all different, so it would need a lot of work to make them compatible, which would be different for something like A and C stock where the braking arrangements are quite different - in that sense 62 and 92 stock share more similar braking characteristics than A and C stock. What could be a little more feasible is running the vehicles between battery locomotives, not under their own power.

New York has the Train of Many Colors which is a train made up of different stock cars, but I assume the NY subway system is more uniform!

What could be a little more feasible is running the vehicles between battery locomotives, not under their own power. Its possible with a lot of work, and replacing a lot of gear. There is different control gear amongst stock, and brake gear like said above. 62TS can control 92TS purely because it has an encoder so it can control the brakes, but the 92TS would be unpowered. You do not want different types of motor running together, as they have different gear ratios and acceleration curves so such would not all move at the same pace.

I suppose that, if someone were to put up the money that a trailer vehicle with compressors and electronics translators could be constructed to run between the two.
It could be designed, above sole bar level as a replica of some stock that was never preserved (F stock comes to mind first).
I doubt it would be cheap though and I have no idea what regulatory approvals would be required.

Generator wagon in style of later bodied Q stock, so they can run at heritage railways. Whether they have the money for it is another issue.

Pleased to say the restoration of BEA coach MLL738 is as complete as it can be, now restoring MLL721

The only mixed stock that could run together was Q stock variants and separately standard stock variants, hence the term "standard stock" though it was far from standard!

We know that R stock will never run again, as there is just one DM left.
But what would be great is if it was connected to electricity and air so that museum visitors could see the lights work*, hear the whine of the control gear and see / hear the doors opening and closing (even a single guards' door would be great although a double door would be even better).
If it was possible, locating and refitting one of the unique guards' panels with the key that travelled in a semi-circular direction would also be great.
*A precedent for this exists at the LT Museum with the 1938 tube stock.

Simon There's two R49 and one R38 DM. As I've pointed out before on other posts on this forum, multiple units of various LT Stock LPTB era onward have been preserved except prototype stock. A60/62 Stock breaks ground on being first Stock to have only one DM preserved. To make most preserved stock operational again under it's own power, you ideally need two DM + T Sets. Coupling two different variants brings it's own set of challenges.

There's multiple 1967TS Stock DMs under preservation. Many that were in storage have been scrapped but LU still have a few others that will be converted for further use on LU metals. The AIT will be scrapped however.
