The VAL 208 is one of the VAL series, an automated guideway transit system developed by Matra and Siemens. The vehicles are manufactured at Siemens SGP (Simmering-Graz-Pauker) in Vienna, Austria.

It has been adopted by multiple railway operators since 2000.

The number 208 in the name comes from the fact that the width of the vehicle is 208 cm.

In the successor to VAL 206, the system is compatible with VAL 206. Normally, automatic operation is performed, but it is possible for the driver to manually operate as necessary.

Overview

Because of automatic operation, the delay is small, the train density can be increased. On the other hand, since this train is basically a two-car train, it is suitable for low-population areas and medium-sized cities.

Interior

Although the vehicle is small, the window is large, so it is a car with open feeling. According to the climate of Europe, although air conditioning is not installed in the basic specification, air conditioning is installed only in the Uijeongbu Light Rail Transit train at South Korea.

Plastics are widely used for many parts, but doors and handrail are made of stainless steel.

The color tone inside the car varies depending on the railway operator.

Traction equipments

Bogie

The traction control system does not adopt the VVVF control, and it has become a conventional chopper control.

The traction motor adopted Alstom's brushless DC motor. The traction motor was self-ventilated, mounted on bogie. It is mounted inside each wheel, and the power from the traction motor is transmitted via the planetary gear and the Cardan joint mechanism.

VAL208NG

A minor change has been done several times in VAL 208, and a major change in specification was made in VAL 208 NG which is a minor change car in 2006. Specific changes are as follows.

Abolition of VAL 208 logo
Abolition of the Matra logo that was on the door
Reduction of noise by reviewing traction motor specifications
Change of structure of the door
Weight saving

gollark: Google has a thing called "SafetyNet" which allows apps to refuse to run on unlocked devices. You might think "well, surely you could just patch apps to not check, or make a fake SafetyNet always say yes". And this does work in some cases, but SafetyNet also uploads lots of data about your device to Google servers and has *them* run some proprietary ineffable checks on it and give a cryptographically signed attestation saying "yes, this is an Approved™ device" or "no, it is not", which the app's backend can check regardless of what your device does.

gollark: The situation is also slightly worse than *that*. Now, there is an open source Play Services reimplementation called microG. You can install this if you're running a custom system image, and it pretends to be (via signature spoofing, a feature which the LineageOS team refuse to add because of entirely false "security" concerns, but which is widely available in some custom ROMs anyway) Google Play Services. Cool and good™, yes? But no, not really. Because if your bootloader is unlocked, a bunch of apps won't work for *other* stupid reasons!

gollark: If you do remove it, half your apps will break, because guess what, they depend on Google Play Services for some arbitrary feature.

gollark: It's also a several hundred megabyte blob with, if I remember right, *every permission*, running constantly with network access (for push notifications). You can't remove it without reflashing/root access, because it's part of the system image on most devices.

gollark: It is also worse than *that*. The core bits of Android, i.e. Linux, the basic Android frameworks, and a few built-in apps are open source. However, over time Google has moved increasing amounts of functionality into "Google Play Services". Unsurprisingly, this is *not* open source.
