Yes. 12171/72 don't halts at gwalior, aur news link bhi aisa kuch mention nahi karta ki ye train wahan halt karengi, bas ye likha hai ki "pass" karengi.
22222 could have been an option, but god knows why ain't they running trains between delhi-mumbai via central line. Only train available right now is Mangla Lakshdweep Express.
12171/72 ka proposal NZM terminate karne ka tha. wo bhi shayad approve nahi hua abhi
