Yeah, you are right. That is why I was trying to say that this maybe the reason for not having a MYS-MAQ train.
There is something very interesting about MH Railway (MG). It is probably the only railway line in the world which lasted for a very short time. It started operations in 1979 after some 10 years of work. In 1997 it was closed for conversion till 2007. So a line which too 10 years to build lasted only for 18 years.
