The bigger problem is that where will the 2 rakes be kept?
No space at Alwar or any nearby station
Taking the rakes back Rewari might not be a very wise decision
That's why Alwar Jaipur express runs in the afternoon and not in morning time when its required
But...
more... that still works out because people going to Jaipur in the morning use Ranikhet
But still a train for JP is required to run at six in the morning but not possible currently due lack of pit lines/platforms/terminal facility
