Looking at the layout and some assumptions so far (that the rear facility is a train station, that the East facility is the indoor E-ticket, and that the West facility is where the shops and Hades dinner show are, some questions come to mind:
1. If the train station is an outdoor, visible freestanding structure, as typical in Disney castle parks, that scale of structure doesn't seem substantial enough to be the landmark "weenie" at the end of the village. Of course it can have a tower, and I'm hoping that the land has a clock tower and humorous glockenspiel show, but why have the building oriented obliquely to what appears to be the town square?
2. Yes, I get the train station needs to have a loading platform parallel to the train tracks but the frontage of the structure could face the town square while the platform at the rear is parallel to the tracks (see the "alternate shape").
3. Or, the train tracks could have more of an 'S' curve as at Disneyland (post SWGE) as seen in green and the building as designed could be rotated to face the town square.
4. But even more of a question, why would the train station be the weenie and focal point anyway? Yes, the railroad is an important part of the park but it's hard to see it as central to the Villains theme or placemaking, and the aesthetics of the train chugging along the back of the land (if visible) and the train station being the weenie, would seem to be a non-sequitur. Why the emphasis on that? Is the train station and bright red train what they'd want showing up in the photos looking down the town square, roughly where Hogwarts Castle is in Hogsmeade. I find that very surprising.
4. But one way I can understand it is if the train station is actually an "underground"/tunnel train station in which case this building has an interior themed as a cave and the structure is concealed behind rockwork anyway and the orientation is irrelevant...allowing the railroad tracks to take the most direct and efficient path. In this case, the train station isn't visible and isn't the weeine. but rather the mountain, forced perspective Maleficent castle, etc. would be (behind it).
5. But another question I have is around the common assumption that the E-ticket is going in the East facility. I understand why that would seem likely, it's the biggest building. But that would then make me think the Hades dinner show is in the West facility -- where else would it be? (If it was also in the East facility, that would reduce the space for the attraction significantly.) So the issue is: if the Hades dinner show is in the West facility, how will the train tracks run through this building? Even if the track/tunnel is at the back of this building, isn't that an obstruction to kitchen/backstage operations to support this restaurant and likely neighboring retail? I guess the kitchen could be at a lower level than the track, it just seems complicated. It's a smallish point but it's a reason why I think the West facility may be a show building more than a facility for retail/F&B. We've seen them run tracks through show buildings.
