Rail terminology: Multiple unit vs locomotive traction

>>1087934
> * Concentrated traction EMU: 1-2 leading/trailing power cars hauling

>>1087934
Not really.

Distributed traction is where the power is delivered to the rails on many/most axles. Cl43 have their traction motors just in the power cars, i.e. concentrated.

>Concentrated traction EMU: Power cars hauling passenger cars in the train set (Acela, TGV, ICE-1)
>Concentrated traction loco-hauled train set: Locos use in general, including push-pull (eg BR Class 43 for Intercity 125 HST)
Don't see that much difference here (aside from electric vs. diesel)

>>1087994
Ah sorry I didn't translate the word properly.
Would it be correct for "power"?

>>1088003
I understand BR Class 43 is seen as a loco more than a power car and HST isn't permanently coupled, so used it as a convenient example.

>>1088049
Don't really know much about brit railways, did the class 43s ever pull anything but the HSTs in revenue service?

If so, I can see why you differentiated between it and Acela, TGV and ICE (>>1088003 was a test run, no a regular service).

>>1087934
Eh, there really isn't anything permanent about MU'd engines. It's easy and simple to break them apart.

You're also forgetting Distributed Power or DP. You know, where you link engines together with a radio and control multiple consists within one train.

>>1088057
Meant multiple units not MU locos.
> * Distributed X(don't know the right word) loco-hauled train set: Distributed power and MU control loco

The Intercity 125 was originally called the "Class 253" and was officially a multiple unit.
However, today power cars are "class 43". The coaches are "mark 3". The entire set is an "HST".
The class 43 power cars are not used for anything else other than hauling fixed amounts of mark 3 coaches in top and tail formation.

>>1088208
So sorry but, is it considered a multiple unit now then?
I'm don't know much about UK rail.

I find it weird that China trying to use the term "EMU" to differentiate comparatively higher speed train from HST

As I said, it was originally known as a multiple unit but now not so much. This is because each set has 2 locos and a rake of unpowered mark 3 carriages which can be added and removed easily. Multiple unit has moved on from being anywhere near loco hauled like the HST and now only is used to mean distributed power and permanently coupled sets.

>>1088296
That word is a very funky one even in Chinese languages. PRC Chinese is artificially constructed arbitrarily and linguistically distorted. No sense.

>>1088409
Thx.

EMU= Electric multiple unit
DMU= Diesel multipe unit
been around for ages, not even chinese in origin

It's about "動車組" D-trains if you don't know what we are talking about.

>>1088474
Ahh didn't notice.
