See what I think is they are more bothered about the Frieght corridor which is happening in full swing.
Coming to the Doubling of the tracks, ya it is happening at ok speed, they are giving final touch in the Ajmer-Sojat-Marwar section.. Marwar-Falna section work is still in the early stages....
Last but not the least the electrification doesn't seem to be happening in this particular section (Ajmer-Marwar) for now....
