The Italian locomotive FS Class E.636 was an electric locomotive used by the Italian Ferrovie dello Stato (F.S.) produced from 1940 to 1962. All locomotives of this type were taken out of service by 2006.

OverviewEdit

E.636 replaced the all-purpose locomotive E.626 and the E.326 FS express locomotive. E.626 was the first Italian locomotive with the axle arrangement Bo-Bo-Bo, and used a two-piece box for the middle joint of the center truck. This system was later used in locomotives E.645/E.646 FS and FS E.656. It adopted the axis suspension system and was associated with the location of a substantial part of Italy's rail routes in the mountains. E.636 locomotives can be equipped with a gear ratio of 21/65 providing a top speed of 95 km/h (locomotives operating heavy goods trains) or 28/65 to ensure maximum speed of 120 km/h (locomotives operating passenger trains ) .

E.626 locomotives were produced in three series :

  • the first series ( locomotive number 001-108 ) in the years 1940-1942
  • the second series ( 109-243 ) in the period 1952-1956
  • third series ( 001-008 ) in the period 1957-1962

The first E.636 entered service in May 1940. A total of 469 locomotives were built in this series. Six of them were destroyed during the conflict, and after the war, in rail accidents.

E.636 series locomotives were used at the beginning of the twenty-first century. Although it had already been outdated, it still handled cargo in Sicily. Some of them were also given to smaller Italian railway companies. The last of the locomotives were withdrawn from use in May 2006.

HistoryEdit

Towards the end of the 30'years the Italian railways could rely on the use of three types of electric locomotives to 3000 volts DC power, they are designed with a philosophy of " interoperability ", and projected by the engineer Giuseppe Bianchi. His design was chosen to allow the full compatibility at the level of components, electrical and mechanical parts between the various types of locomotive in favor of greater versatility and lower maintenance costs. Then we had the E.626, produced in 448 samples between 1928 and 1939, the classic locomotives "handyman" service since the late 80s, of which there are still in 12 units classified as " historic rolling stock " and these are predominantly type representative. At that time, these locomotives were used in the most varied services for both passengers and goods with just enough performance, but they had a weak mechanical part, so it was fitting that the E626 did not exceed 95 km/h, although in testing it had been reached 110 km/h of speed with no apparent problems. At that time it was tested a new group of locomotives, the E.326 , designed for high speed (140-150 km/h) but it soon turned out to be unsuitable for this purpose because of the significant step drive, the wheels of considerable diameter and of a mechanical transmission that suits means that not tranviari rail. Their low mass adherent, a harassing effect "resonance" and other problems sway in straight line did the rest, making sure that the project E.326 was limited to just 12 examples, however, they heavily damaged during the 2nd World War and which were later rebuilt. Finally the Italian railways had at their disposal the unforgettable group of E.428, huge , powerful , versatile , strong of their 2850 kilowatts but absorbed by the low mass adherent caused by the type of running gear.

The first locomotive E.636 entered service in May 1940. A total of 469 locomotives were built in this series. Six of them were destroyed during the conflict and after the war, in rail accidents.

E.636 series locomotives were used at the beginning of the twenty-first century. Although it had already been outdated, but it still handle bonded cargo in Sicily. Some of them were also given a smaller Italian railway companies. Recent locomotive series was withdrawn from use in May 2006.

Now this locomotive is a locomotive of historical interest and few specimens are preserved at the La Spezia's (Liguria - Italy) railway museum.
