Mallard BASIC
It was also optimised for speed it is named after the LNER A4 class 4468 Mallard locomotive, the fastest steam locomotive in the world, once again displaying the company's fondness for railway-oriented nomenclature. (For instance, see the company name itself.) In fact the Locomotive name came from the phrase "To run like a train" and it was this theme that was used to name Mallard BASIC no other Locomotive product was named after anything railway-oriented.
VR Class Dr12
When it was introduced, the Dr12 gave drivers a new experience of comfort and forward visibility compared to steam locomotives, but compared to the newer VR Class Dr13, the Dr12 had a heavy axle load and slow acceleration with a top speed of only 120 km/h. The reason for this was that the locomotive turned out to be underpowered. The problem of the top speed was corrected in the last 10 locomotives by changing the transmission in such a way that the technical top speed was increased to 140 km/h, but this feature was never used. As a result, the entire locomotive series had a maximum permissible speed restricted to 120 km/h. However, due to the high axle weight, the Dr12 had good adhesion properties and it was considered to be a reliable and robust locomotive. It was well-suited to heavy trains with relatively low speed requirements.
