1 They arrived this morning.

2a What time does the train arrive in London?
2b They've taken a long time to arrive at a decision.

The choice of ‘at’ or ‘in’ after arrive depends on how the next word is written: we use ‘at’ before common nouns, which normally start with low case letters (minúsculas), and we use ‘in’ with proper nouns, which usually start with CAPITAL LETTERS (mayúsculas), except for country names that start with ‘the’, like ‘the UK’, ‘the People’s Republic of China’, ‘the US’, ‘the Netherlands’ and others, e.g.: They will arrive in the UK in two hours.

Besides, there’s a series of words that don’t require ‘in’ or ‘at’, like: ‘home’, ‘here’, ‘there’, or ‘downtown’.

🌱Noun: arrival.
☣️Remember: We never use arrive to.

16a When I got to the station, the train had left.
16b The news didn't get to me until this afternoon.

24 He's very ill. We must get him to hospital (get him home).

Get to is often used as a synonym, although originally it implied more difficulty than the others, e.g. in the journey to the station or in the speed of the news reaching me, see sentences 16a and 16b.

As it happens with arrive, we have a bunch of words that don’t need ‘to’, like: ‘home’, ‘here’, ‘there’, or ‘downtown’.

2a. What time does the train reach the station / London?
2b. Can you reach that book on the top shelf?
2c. They've finally reached a decision.

3 The news reached me just as I was going out.
  Can we reach (contact) him by phone?

Note the direct object, without preposition, in sentence 2.
Reach can mean ‘to be able to touch, or to get down’, like in sentence 2, and that is why we have the prepositional phrases ‘within reach’ and ‘out of reach’ (that can or can’t be reached).

🌱 Noun: reach, the distance you can reach or the length of your arm, e.g. You have a longer reach than I have.
