“A spatial equivalent station to” vs. “a spatial equivalent station as”

Question

The second working period shall either start at the same station or in a spatial equivalent station to the first working period's start station.

I'm in doubt regarding the preposition to used above, because I kinda feel that the preposition as would also fit there. But I'm not sure which one to use or why use one instead of another.

Answer 1

The collocation is equivalent to. I can't think of any context in which equivalent as would be used instead.

I'm not sure what the sentence is about, but it sounds very legalistic. Perhaps it's meant to, but, in any case, you probably need spatially equivalent rather than spatial equivalent.
