Train company tours are affected (8)

I believe the answer is:

eurostar

I'm a little stuck... Click here to teach me more about this clue!

'train company' is the definition.
'eurostar' can be an answer for 'train' (I've seen this before). I'm not sure about the 'company' bit.

'tours are affected' is the wordplay.
'affected' indicates anagramming the letters.
'tours'+'are'='toursare'
'toursare' is an anagram of 'EUROSTAR'.

Can you help me to learn more?

(Other definitions for eurostar that I've seen before include "Waterloo to Paris train" , "Railway service via the Channel Tunnel" , "Channel tunnel rail service" , "High-speed rail link between the UK and France" , "Chunnel service" .)

I've seen this clue in The Times.
