The key advantage is that sending signalling information over GSM-R is akin to the old dial-up technology, which hogs the radio channel and prevents anyone else from sharing it for voice calls. GPRS is akin to switching to broadband, in that the GSM-R channel can be shared with the signalling network.

In terms of modern signalling this is as cutting edge as it gets; it's like moving from a Nokia 3210 to an iPhone 16. It effectively allows our drivers to see around corners.
