The class E 10 is an electric locomotive of the Deutsche Bundesbahn introduced in 1952. It belongs to the so-called Einheits-Elektrolokomotiven (standardised electric locomotives) program and was built for express passenger trains. After 1968 it was renumbered as class 110 and class 112. Later classes 113, 114 and 115 were derived.
Development history
In 1950, the Deutsche Bundesbahn decided to introduce two general types of electric locomotives with standardised components: A twelve wheel (UIC: Co' Co') freight train locomotive based on the class E 94 and an eight wheel (UIC: Bo' Bo') general purpose electric locomotive based on the class E 44. As a new feature the engineers should be seated, whereas formerly they had to stand.
In due course of the construction the to speed requirement for the general purpose locomotive (working title E 46, then changed to class E 10) was increased to that point that the layout was one for an express train locomotive. Two types were not found sufficient to cover all needs, so the Einheits-Elektrolokomotoven program was changed to four general types: Light passenger train locomotive (class E 41), express train locomotive (class E 10), freight train locomotove (class E 40) and heavy freight train locomotive (class E 50). All four classes should share a maximum of standard components. In addition plans for a high speed electric locomotive class E 01 were made, but quickly cancelled, as at that time due to low maximum speed on the main lines the class E 10 was seen as sufficient for express trains.
Production of class E 10
The five prototypes of class E 10 were the first of the standardisation program. They were used to test various different components. All prototypes were taken out of services between 1975 and 1978. Of these class E 10.0 the E 10 003 and E 10 005 were preserved.
The first serial units went into service in 1956 and started with number E 10 101 (class E 10.1). In difference to class E 40 they were also equipped with an electric brake. Maximum speed was 150 km/h. Starting with E 10 288 the body form was changed to the one used with E 10.12 (see below), the so called crease type class E 10.3. All class E 10 were in 1968 renumbered to class 110.
Class E 10 went into service with express trains. After introduction of class E 03 / class 103 and especially of class 101 the units were used for local trains. Many units after 1997 were equipped with push-pull train controls, partly using components of class 140 and class 141 units that were scrapped.
In the beginning class E 10 units were painted blue, as a sign for express train duty. Since then they have seen another three paint schemes, thus underlining the solid construction that allowed them to stay in service some 50 years. But class E 10 numbers are decreasing every year, as they are replaced by new class 146 and EMU units.
Construction
As all other types of the Einheitslokomotiven program the class E 10 had welded bogies with central pins. Instead the formerly used cannon box engines it used the Gummifederring (sorry, unable to translate) power transmission, that in class E 10 prototypes worked extraordinarily well and smooth. The control unit comprised 28 possible power settings. The driving motors are type WB 372, the same one being also used for next generation class 111.
Variants
Class E 10.12 / class 112
Some E 10 during production were equipped with new bogies fit for 160 km/h. In addition the design of the body form was changed (and starting with E 10 288 also apllied to all other E 10 units). The class E 10.12 were used fpr fast international trains such as the TEE Rehingold. A total of 31 class E 10.12 / class 112 units were built.
Class 113
In 1991 it became obvious, that the changed useage for heavy local trains instead of light express trains took its toll for class 112. After in some cases gearbox failures heavily damaged locomotives, the maximum speed was reducrd to 120 km/h. At this time the units already had been renumbered to class 113, as former GDR Deutsche Reichsbahn class 212 units were renumbered to class 112 (new). By mid-1990s the bogies were repaired, so class 113 now is back to maximum speed - but due to the low number of units for economcial reasons they will be put out of service soon.
Class 114
Former class E 10.12 units 112 485-504 already in 1985 have been restricted to a maximum speed of 140 km/h and in 1988 renumbered to class 114. Due to remaining high abrasion the speed was farther reduced to 120 km/h and then the units were pulled out of service. In exchange they were equipped with bogies of class E 10.1 units and put back into service. The class E 10.1 units were equipped with bogies of old class 140 units, thus creating additional class 139 units and thereby proving the usefulness of the concept of standardised parts.
Class 115
Starting in 2005 some former class 110 and class 113 units were purchased by DB Autozug, the DB subsidiary for express trains with car transportation. In order to discriminate these units from the others they were renumbered to class 115.
