17057 is quite good train and one of the safest to travel here in this route (others are Ajanta and Sachkhand).
Devagiri is bit slower but still gets the utmost priority here in this Single section.
Book without hesitation in this train. But a Word of Advice, Fooding options will be lesser in this train in this route. Specially the Lunch Next day as Nizamabad is not that much having better food facilities.
