KTM Intercity is the company. 
Anyway, Intercity got a few types. Express, Mail and Shuttle. To
briefly summarise, Express stops at major stations. Mail stops at
all stations and halts when needed. Shuttle stops at major and
minor stations. Stops varies with each train.
They should rename the company as KTM Berhad and remove all the
jargon...
Then go into restructuring, use English as the main medium for
future expansion. Rename services in English.
