Don't change the name, it fits far too well. Unless there's already a TF2 map using the name? It'd be a shame if you changed it because of a map in another game and leave it unusable by everyone else.
After playing this a couple of times now, I can say I like it but I like defending a lot more. It's a lot easier (mostly on second) to win as defense in my experience, if you just get 2 engineers who aren't brain dead. That isn't to say RED wins more, just that I think they could--and would if this map was released into Valve servers, for instance. I know the best spots are easily outranged, but if you have a couple covering each area, it gets really hard to push in. Especially if anyone wrangles.
By request, some gripes:
I'd like there to be a decent sentry spot behind this wood wall somehow. Most of my complaints focus on the building between A and B, so perhaps you'll figure out a way to create a spot or rebuild the whole thing or something, idk. I don't know how a sentry could sit there now and be useful, but it seems like you should be able to do that, but you can't. It can get shot at from far off pretty easily. Same if you put it over the point in the window thing.
I pretty much hate being in this area. The two ramps are total trash--so long, one is super narrow, they are way tall, you just end up walking into enemies and dying a lot. Plus it's cramped generally in here, so splash hits a lot more often. I'd like to see the skinny ramp either removed or heavily reworked; it feels like you ripped it from a Quake map and it gets in the way of a possibly useful sentry position in the window.
I hate this corner too. I can't tell you how often I got trapped here and died to bullshit or just slightly messed up moving around and got stuck in that little 48u corner or whatever. I feel like cleaning this up would go a long way.
I don't like this part either. I feels bizarrely hard to hold this as BLU sometimes; I think redoing the height so BLU just has the 64u advantage up until this area of the RED side would be better.
While you're at it, maybe move this door to the right wall across from it and make it larger. I'd like for it to be useful, but right now it can't see enough of the battle field to merit using.
I think part of this should be chicken wire or something. Make a rusty alpha channel and paint rust. It sucks not being able to see out of this.
Basically the bulk of my complaints are with that one house. It kinda sucks that so much depends on it but it's really annoying to navigate and hold.
I'd also like to see there be a way into the train room for BLU that doesn't involve the train. Also, half the map isn't really used after BLU gets a forward spawn because they all use the left route; maybe in rebuilding the A->B building you can make it attractive to go more to the right.
I think making last slightly larger might be wise. Adding some planks or pipes or something deeper in the hole, like E on Steel, might also be a cool idea. It reduces the deadly space a bit and allows for some trickier plays sometimes.
FYI, your detailing is really good. It's come leaps and bounds since your maps like Aquifer and older ones I won't mention. That's why I really want you to keep the name. You pulled it off perfectly.
