Train drivers etc right to take endless trouble (7)
I believe the answer is:
railmen
'train drivers etc right' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'to take endless trouble' is the wordplay.
'to' becomes 'ramen' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'take' means one lot of letters goes inside another.
'endless' means to remove the last letter.
'trouble' becomes 'ill' (ill can mean a trouble or problem).
'ill' with its final letter removed is 'il'.
'ramen' placed around 'il' is 'RAILMEN'.
Can you help me to learn more?
(Other definitions for railmen that I've seen before include "Train under their supervision" , "They've made tracks" , "On-line workers" .)
