Makkah metro communications upgraded for Hajj operations

Makkah Metro is one of the railway systems that is difficult for me to use. That's because Makkah prohibits people believing other religions from entering Makkah.
If I enter Islamic, I will be able to visit the city. But, it would cause many contradictions like avoiding to eat pork and to drink alcohol.
So, it won't be realistic to go there.
