2. Please remember to take into account British railway terminology.Oh yes, I do. I bought the Ian Allen and later Platform 5 booklets
since the 1970ies.
MGB 21 - 24 are not ‘EMU’ to most British railway people. The most accurate term for them in UK railway English is probably ‘motor luggage van’I often use the term motor luggage van for the MGB Deh. However, motor
luggage vans are always listed under EMUs in British booklets.
but like the SBB 450s they look and act like locosHowever, SBB's 450s are officially classified as locos and their luggage
compartment has been out of use for many years. Initially the doors had
been painted like other doors (of the coaches) but now they no longer carry a special colour.
and slightly fall into a ‘muddy’ area of terminology because when coupled up to a set of coaches they would probably be termed ‘power car’Power car would be another appropriate term, but this still isn't a
In UK railway parlance, EMU refers to an almost permanently fixedFor many years this was the case for all 15 Deh that now belong to MGB,
as there had been a driving trailer for each Deh available. This changed
with two Bt 2251-52 often used with HGe 4/4" and finally with the new
concept of modules B-ABt added to the Visp - Andermatt trains.
For a long time there had also been fixed consists, e.g.
And they have different couplers within the set.
This is quite different to how 21 - 24 are used. They are frequentlyNo, when in use as power car they are never uncoupled anywhere else than in the workshop. But as most Swiss motor coaches they are quite powerful and can thus be used for other purposes.
Interestingly the development was mostly from motor coaches in near locomotive use towards a pure power car function, as could be seen with SBB RBe 4/4 or BT/SOB BDe 4/4 or even RhB ABe 4/4. But it's the opposite with MGB who, after the arrival of the HGe 4/4" started to use some Deh as locomotive like.
Today mostly two of 21-24 work as EMU with 2253-54 and two work as locomotive replacements. Recently also one or two ex-FO Deh were seen working single.
