These were the first New York Central units to offer air conditioning, with sealed windows replacing the drop sash and clerestory types found on earlier cars. The initial set of 100 cars was retired in 1970, upon completion of the M1 railcar delivery, while the second and third orders, totaling 87 cars, remained in service until 2004, when they ...
High-efficiency all-electric refrigerant compressors for air conditioning are starting to be used, especially in hybrid or all-electric vehicles. The cigarette lighter receptacle serves as a de facto standard for use of portable 12 volt equipment in or near an automobile, it is sometimes used with car charger to power devices with batteries.
The Nash "All-Weather Eye" was the first automobile air conditioning system for the mass market. [2] The use of the Weather Eye name for automobile passenger heating and air conditioning systems continued in American Motors Corporation (AMC) vehicles. The design principles of the Nash Weather Eye system are now in use by nearly every motor ...
Until then, Sydney had lagged somewhat behind other cities that had commenced the introduction of air-conditioned stock. In order to fit the air-conditioning equipment into the motor cars, the pantographs were moved to the trailers, effectively meaning that a motor car must remain semi-permanently coupled to a trailer car.
To accommodate the air conditioning and associated equipment, the pantograph had to be shifted to the adjacent trailer car to which the power car is semi-permanently coupled with high voltage cables connecting the two cars. Although some power cars and trailers have been broken up and married with others during periods of heavy maintenance ...
This is both because of the high power requirements for the air-cooling systems and because the presence of ventilation grates in older stations would reduce the efficiency of an air conditioning system. The Grand Central–42nd Street station is a major exception, since there is a large cooling plant for Grand Central Terminal immediately ...
Newspapers are often discarded onto the existing air vents behind seats, which increases the problem. [11] [12] Conventional air conditioning was initially ruled out on the deep lines because of the lack of space for equipment on trains and the problems of dispersing the waste heat these would generate. Different systems were proposed to cool ...
The Central line is a London Underground line that runs from West Ruislip or Ealing Broadway in West London to Epping in Essex or Woodford via Hainault in East London, via the East End, the City, and the West End. Printed in red on the Tube map, the line serves 49 stations over 46 miles (74 km), making it the network's longest line. [3]
