Train TVA



From the outset, we made ​​the choice of a standard equipment and fully unified for all lines of the Aude. The technique was chastened, separating the complex formulas and especially weight-conscious leaders choosing a simple equipment and inexpensive both to purchase and operations and unified to facilitate maintenance, even if its characteristics were often less than the efforts which it was asked.

General characteristics.

Setting the dimension of the axle was 0.930 m, the height of the central buffer coupling with 0.700 turnbuckles by two on either side of the buffer, the length of the spreader being 0.650. These characteristics ranked networks in the category of low buffering (650 to 703 mm) in the compatibility charts to be prepared by the care of the Army during World War I, category unaffected by military requisitions.
The template material was 2.20 m wide and 3.50 high, the continuous brake chosen was the vacuum brake Soulerin.




There were 030 T machine type 17 tons built from 1899 by the Establishments Corpet and Louvet. Thirty-five machines were delivered to the only department of Aude. They will be designated as "Type Aude 776" the number of the first locomotive delivered.
For single-line Castelnaudary Belpech 4 machines were delivered:
Machine No. 24 was transferred by road to Belpech (15km) to the start of work by the end of the line. The other three No. 25, 26 and 27 were delivered by the Compagnie du Midi in Castelnaudary.
These machines meet the following characteristics:
  • Average tare weight
  • Weight in working order
  • Bell
  • Roll diameter
  • Piston stroke
  • Grid surface
  • Heating surface
  • Length over buffers
  • Width

All these locomotives were subjected to the test because of network operating conditions which were added two other reasons: the endless succession of traction conditions, the curves of small radius succeeding alignments, ramps with gradients, resulting in changes the appearance of the fire very detrimental to the maintenance of the home sky and tubesheet heat, then often a poor water supply quality.



17 March 1906 Park TVA for all the department included:

  • 51 cars, including the lounge car company.
  • 19 vans.
  • 56 seats.
  • 61 trucks.
  • 116 flats including 8 swivel sleeper.

Characteristics of the rolling towed.

TVA on cars, all built on similar two-axle chassis, differed significantly depending on their development. Except for the "lounge car" with 12 seats, there were cars "A" first class of "AB" mixed and "B" second class. 20 freight cars put into service in 1903 were divided into boxcars series "KFVS" with sliding door on each side, in trucks, series "Ifm" and platform series "Hfm". The main dimensions of these cars were as follows, regardless of the class:

  • Frame length
  • Length over buffers
  • Wheelbase
  • Overall Height (roof)
  • Wheel diameter
  • Long. springs (7 blades)
  • Span width (inside)

Material, especially before the Great War was still insufficient. Thus the lines and Bram Castelnaudary, in case of unavailability of a joint car, ticket sales was first removed. And if van unavailable, it was replaced by a canopy. But a car 2nd class should always be available to the conveyor PTT.
These cars were not heated. Following a petition in 1905, users requested the installation of water bottles. The Company holding the equipment too expensive, adopted an intermediate solution by providing the conductor 2 or 3 water bottles the mechanics filled of hot water and were given to travelers who requested them, beginning with those who carried out the longest course.



Wagon type D also used by PTT

The light oil having been criticized, there was talk about 1920, to install electric lighting, but again the price of the equipment was back the Department and the Company. The lamps in use required the officer to move the lighting on cars, what with hobnail boots, the rapidly deteriorating sealing canvases. The TVA envisagèrent then the use of lights, always oil Amall type with polished reflectors, which took place in the flat glass lanterns attached to the inner walls of the compartments, although the quality of the lighting has suffered economies maintenance led to the adoption of the system.
After 1920 the blinds that existed only in the first were generalized and billboards appeared on the roofs of cars second.
