droplight การใช้

• One window was fixed and the other was a droplight.
• Although there were no external doors to the dining saloon, the windows retained the droplight and quarter light arrangement.
• At first there were two such windows in each compartment ( one fixed and one frameless droplight ) in the manner of the characteristic Midland pattern vestibule coaches already considered.
• During Period I, the favoured method of admitting fresh air was the droplight which was frequently supplemented by and finally ( in Period II ) in large measure superseded by the Stones and Dewel pattern glass vane ventilator.
