always report missing translations.

I think it is really "want" ("xiang yao") here. Just "xiang" without the "yao" would be "like".

think like is as good as want here, but I guess I should have added "to get there" even though I knew that's what it meant

Yep, this needs to be fixed.

This doesn't work with "a" in English. I has to be "the". It's not like you have a choice of many subways and just take any old one. With "bus" or "train" you could use either "a" or "the" however.

It means (to) go. Without 去 it would just mean that the person wants to ride the subway (no mention of getting anywhere), with 去 it could be literally translated, "I want to take the subway to go." - but in English we'd say "to get there" instead of "to go".

I wrote "would like" too! And it wasn't accepted.

In a very literal sense, yes, but in these examples, not really. Better interpreted as "take" rather than "sit".

It's more like "to ride" i believe

Yes, sit or take[a vehicle] as in take the subway

"在" literally means "at" and is redundant here. But if you wan to have a literal translation, yes, "我想要坐地鐵去那兒" is correct. (In Chinese "那兒" can be omitted, but in English "I want to take the subway to get there." would be unnatural if you omit "there.")

Yes it is, because you don't often have a choice of subways. In Germany and Japan you might but in Germany you'd always distinguish S-Bahn from U-Bahn and in Japan all the different companies and lines join up into one massive system anyway and typically you don't have an option of which company to take to get to a certain station. Basically we'd never say "a subway" just like we'd never say "a freeway".

We would however say "a bus" or "the bus" and "a train" or "the train" since those can refer to both the individual vehicles and the system they're part of. The individual vehicles in the subway are not also called subways, and that's the difference.

Over here "Subway" recently became a fast food chain. I've never heard anybody call the things they sell subways. They're always sandwiches or rolls. Maybe subs, though that sounds too American to me.

But yeah none of the urban trains in Australia are mostly underground even though some of them have a few underground stations.

Aussies overseas do call them subways or metros though because locals think we're talking about long distance above-ground trains when we just say "train".

Is it only in the UK that it's called the underground?

"去" adds "going" to some destination. "to get there".

I'm not American and I am a native English speaker and I would say "take the subway". I would also say it some other ways, depending on the context.

No. Trains and subways are very different things. Also, train is 火车， not 地铁。

A subway may be an underground tram as well as an underground train. In places that have two systems, people are confused when outsiders use "train" to refer to the underground urban system.

In places like Australia that don't have entire systems underground then yeah we'd say "train".

I agree, because if you live where subways aren't a thing then you just say train. While the Chinese words have different meanings, in class we would always just translate it as "I would like to go by train", because if you don't have subways the two just seem synonymous.
