Something that I have always wondered-why did the 1949 stock (UNDM and trailers) have such a short life? I know that the shunt controls were used in the 1972 stock UNDMs.

But I thought that the 49TS cars went before some of the 38TS DMs. The last 38 in service didn't have 49TS trailers and UNDMs in it.

The only reason I can think of is the obvious; less flexible then DM cars. Plus also as TP has revealed, they were wried in perminant series. Seems like they were jut non standard,

If you consider the 38TS and 49TS as one series of rolling stock, the 49TS were non-standard. The bogies were different (although possibly of better design) and there were a number of detail differences. If you are reducing the size of a fleet of rolling stock, it makes sense to get rid of those that are different.
Similarly, when LT needed to reduce the size of its RT fleet, it sold RTLs (different engines) and the Cravens RTs (very different body).

That's what I presumed. Take the Northern Line. The 56ts was scrapped in the mid 90s and replaced by some 62ts. The newer 72mk1s were also withdrawn first too.
When did mass withdrawal of the 38ts begin, 1975? replacement with 1973ts?

The 72 mk1 stock allowed it start; it continued through the mark2s, the 73ts, the depression, and the 83ts.

The first 1972 Mk 1 entered service in June 1972, and the mass scrapping of the 38 stock began about the same time.

RTLs also had different chassis (Leyland PD instead of AEC Regent), and they weren't that non-standard - there were over 1,600 of them. They went because the garages did't like them as much as the AECs. Some AECs with standard bodies were sold before the RTLs and RTWs More information: www.countrybus.org.uk/RT/RT.htm |

The bodies on the RTLs (PD2/1 from memory) were interchangeable with RTs. Howevr the 8' wide RTWs (PD2/3?) were wider. In addition there were the three batches of RLH low-height Regent IIIs which were completely different again.
I would have said that the RTLs went with first RM then RML introductions, and the RTLs that were not flogged off overseas or to private operators were ideal as trainers.
I remember standing at Reading main WB platform in 1976 or 77 waiting for a HST to Bristol Parkway (and College) and seeing a Class 47 on the Down slow with a long train of 1938 stock going for scrapping. It was a sad yet impressive sight. I suspect that there were two train's worth with barrier vehicles front and back.

As mentioned already, when scrapping a fleet, the non-standard cars go first, together with any vehicles stopped for defects, problem units and anything which will give you trouble.

The UNDM & 27 Standard trailer units went first as they were non standard,then,once 28 trains of 38TS were EHO'd for the Bakerloo the rest of the 38TS fleet went.

Not forgetting the unit "round the back" which had been robbed to extinction.

Indeed, and as mentioned on another thread the 35ts has to be included too.
Ah yes; what were seeing now with 5137...

How similar were the bogies on '49 stock to the ones that came later with the '56 and 59/62 stock?
