MITRAC, it's called. I don't know what the Aventra software is called, but the bodging of MITRAC was why the 345s were delayed, which in turn was why the 710s were delayed (cos the needed a watertight brand-new software system).
Be careful when throwing brand names around.
It is all Mitrac, Electrostar*** Capitalstar and Aventra.
But that is because
(1) Mitrac is a brand name from another part of the (ex)Bombardier business for a large range of rail traction products
[ii] the product(s) migrate and develope as needed, both generically and for bespoke applications, and not and never have been fixed static products cast in stone and set forever
[iii] Mitrac is hardware components and software elements and the two may or may not progress together
(iiii) Mitrac sub elements are often annotated by suffix letters e.g. Mitrac -XYZ will be a specific item; usually an in house (ex)Bombardier job where they are the prime contractor will be all Mitrac so suffixes omitted in publicity blurb (hence skipped in trainspotter ABC books or the like of wikipedia) but more often you will find -ABC or -XYZ mentioned when supplied to work with a.n.other builders trains
As other GB examples of the Mitrac product name wide range, LU S stock and 2009 stock are Mitrac, as are the upgraded 9800 series of Eurotunnel BoBoBo locos ex-9000s as Mitrac as well as all their 9700s; LU 1992 stock is get Mitrac motors and Mitrac control on their CLIP upgrade.
Not even electric traction specific: 172s /somewhere/ have Mitrac elements in their systems; not sure about Turbostars but suspect they do.
Mitrac, like Electrostar, is a former ADtranz product, it has been around that long.
