Where vs Where from?

In this sentence, I think "where" is better but which is not wrong, as where refers to the location of the station and which refers to the station itself. So, from where in this means "from at the station" or "from where the station is" and from which means "from the main station".

How do you use where?

We use where as a conjunction meaning 'in the place that' or 'in situations that'. The clause with where is a subordinate clause and needs a main clause to complete its meaning. If the where clause comes before the main clause, we use a comma: Where you find a lot of water, you will also find these beautiful insects.

Were vs where in a sentence?

Were is the past tense of be when used as a verb. Where means in a specific place when used as an adverb or conjunction. A good way to remember the difference is that where has an "h" for "home", and home is a place.
