Two different companies employ them: Trenitalia and Ferrovie Nord Milano (FNM). Some slightly modified version of the EMU have been purchased by Moroccan Railways in 2006.[1]

Description

Each train is formed by fixed sections of four bi-level pieces: two motorized units (ALe 426/506) and two coaches between them (Le 736). Two sections can be coupled together, but by now it is not possible on Trenitalia units (on FNM ones is common practice).

The total capacity is of 469 seated and 372 standing passengers.

Specifications

ALe 426/506 employs asynchronous three-phase traction motors feed by the 3000 V DC catenary. Motors are mounted on one bogie per motorized unit, for a total of two motorized bogies per section.

Operators
gollark: How coltraniously excellent.
gollark: øøøø.
gollark: I'm sure you'd like me to think that you'd like us to think so.
gollark: Also use of most of this (https://github.com/satwikkansal/wtfpython) and the mildly exotic features like decorators.
gollark: If I were to enter this I may deliberately write my programs in the most stupid and ridiculous way possible (or at least I find it favorable to claim that now maybe), such as by, for example, using preprepared pickle streams for arbitrary code execution, doing everything in one line, horrible overuse of `exec`/`eval`, using that thing where python will execute code from a ZIP concatted onto an image, downloading data from pastebin or whatever, blatantly ignoring all available Python style guides, or mucking with the AST module and importlib to transform the code into other stuff.
