Hi
I am curious as to the formation of the T sets particularly from the 1950s onwards. I am aware that they ran in both six and eight car formations. Extensive viewing of the WTT do not reveal any specific formations for these trains. Photos are not that clear either. I know that there were essentially four types of coach: Motor coaches, Driving Trailer Coaches, Nine Compartment Trailers and Seven Compartment (ex First class) trailers.
Was it a case of a Motor Coach at each end and a random type of trailers to make up the numbers? I am aware that the Met service no longer had any uncoupling in service by this time which I think was the original reason for the Driving (Control?) Trailers? Were these just used as conventional trailers after that or were they still formed in the middle of the trains to enable a set to be split into two halves as necessary-shunting etc in depots. I am assuming that the Chesham branch shuttle was formed with a motor, trailer and driving trailer?
If I have read Snowdon's "Met Railway Rolling Stock" correctly in later years there were no restrictions on any of the different types of traction motor/ gearing being used together in the same train. Am I correct in reading the text this way?
To go off on a tangent slightly- the loco-hauled trains of 'Steam' stock appear to have no fixed formations either during the last fifteen years of so. It seems that as long as there was a brake vehicle at each end of the set, the remaining coaches could be formed of either of the two all third types- the nine or seven compartment varieties. Was there any distinction between the two types of brake third either? Photos of the period do not seem to reveal any set type of formation..
Thanks for any assistance.
