if I am right, when this train terminated at jodhpur instead of bgkt, its time was 5 pm only. When it was terminated at bgkt later on, no there was no change in timing. Ideally the timing should have been 4:50 pm. Effectively, IR is doing no change in the schedule of this train. It has just done cosmetic change in the TT and charging extra from pax.
I don't know what's that problem in actually speeding up this train as there is a lot of slack in it if compared to other SF trains like suryanagari which has much more stops than 19065/66.
