What type of windows were there on a 1930's steam train carriage

sash windows?

square ones.

oh dear that is a toughy - well they definitely were not triple glazing!

When l think of a old fashioned carriage - the sort that had lots of 6 seater cabins off a corridor down one side - l see the window to be made up of a large lower window, with the top say 12 inches being a separate window split into four sections. The two outer sections were fixed in place, but in the centre of the upper window, there were two sliding windows about 12 inches square that slide apart to open, & had a catch in the middle to keep them shut.

Hope that helps??!!

edit---OK just looked on ebay for some model railway carriages & found this one which kinda confirms the senseless waffle l wrote above!!

In UK carriages of the time the main windows slid down into the carriage body. They were operated by a leather strap - a bit like a vertical belt - it had holes every so often & there was a stud below the window so u could stop the window at whatever level was most comfortable bu putting the strap hole over this stud, thus holding the window at that level. There were also smaller opening windows in some carriages - small narrow ones above non-opening windows - which could be slid apart

Are you actually asking if it was toughened glass fitted in 1930 then the answer would have to be no.

There were 2 types basically.

The first was a traditional compartment with a central door to the platform & 2 narrow windows either side, a design that was inherited from stagecoach days. The side windows were called sidelights & the window in the door, because it could be raised & lowered, was called a droplight.

In the other type of carriage the doors were at the ends only, there was a gangway or corridor running through the carriage, & the windows were of a larger, more or less square format with sliding ventilators at the top. The ventilators were designed so that opened a certain distance apart they would not cause a draught, & the position was marked with small arrows.

Look at photographs ,door windows were full drop saloon windows were often twoway slides
