@Ian,
I can not disagree -- it is always a good idea for fairy inventors (along variant game inventors) to investigate preceding fairy elements with even remote similarity.
For fairy composers, rewards can be reaped from improved familiarity with the expanding palette.
Unfortunately, this endeavor seems to require nearly a lifetime; the time required could be substantially reduced, if we (the enthusiasts) establish logical groupings of our fairy elements, and work to make the defaults more consistent.
I view Parrain Circe as a delayed version of Equipollent Circe, and Contre-Parrain as a delayed version of Exchange Circe (aka PWC).
It is unfortunate that our naming conventions do not reflect these relationships -- these four elements could be reduced to a single idea (much easier for beginners to learn, and for veterans to remember); this would be particularly true, if all default rules were made consistent (e.g., pawns reborn onto the 1st-rank should default to a universal behavior). Change would cause no harm to existing compositions -- it merely requires the addition of a single, universal fairy element (something so arbitrary can hardly be considered a penalty). In fact, a systematic treatment would only expand the palette of elements, which would provide a greater diversity of problems ideas.
It is true that Locomotives has some vague similarities with Siamese-Units, and Imitators.
Its relationship with Dynamo, and with Parrain Circe, are undeniably more pronounced.
We should strive for a foundation which allows us to efficiently describe similar elements (as is done for various 'Circe Modalities').
Yet, the inherent nature of the Locomotive definition may provide compelling reasons to diverge from the defaults of these precedents.
As you say, there are times to prefer consistency, and times to favor distinctiveness.
The trick to playing chicken is knowing when to veer off (there are defaults which should keep consistency with the past, there are ideas which inherently suggest a need for distinction, and there may be instances which require foresight into future possibilities).
The important thing is that we let logic do the driving, anticipate the need for changes, provide a modular foundation (where alternatives can be expressed), listen to competing perspectives, and find agreements (build a foundation on common-ground) which can be sanctioned by the proper authority.
We should also encourage minimum sets of problems, which illustrate the myriad of special case possibilities (for all fairy elements, and every alternative interpretation). In my experience, it is generally better to start with the Valladaos (problems showing Allumwandlung rarely teach us anything beyond the general rule).
@All,
I presume that the train is a function entirely based upon the move-vector (departure-square, destination-square).
 (= 3+1 )
 = Moose
Locomotives
Thus, after the diagrammed moose moves to d7, the white King should be pulled to f3 (not the wP pulled to g3) -- 1. Md7 (wKg1->f3) -- agreed?
I further presume that any intermediary steps required for a move are neglected (the rebirth vector is only a function of departure- and destination-squares).
Also, as already mentioned, I presume that the distinction between pushing and pulling is based entirely upon a unit's relative location to the departure-square (with respect to the directional vector).

@Jacques
I do indeed have some options now, and will write up a list of rules.
@Ian
I was unaware of Siamese Pieces. I looked up some examples on Juraj Lörinc’s website, and it seems as if the Siamese units must be of the same type. Is this so?
@Kevin
You raise an important question with your moose scheme. I think what you propose is sensible, as it avoids unnecessary complications. The departure and arrival squares (not any intermediary squares) determine direction and distance, as well as identification of freight cars. So I agree with 1 Md7 (wKg1-f3).

@Linden,
Right, that is consistent with Equipollents- and Parrain-Circe; perhaps some other conditions, too.
As for Siamese units: they are tied together, and they do not "pull" on lines (completely different animal).
