  We explore nonrelativistic limits of $\mathcal{N}=1$ quiver gauge theories in
5d. The stringy counterpart of these SCFTs is characterised by torsional string
Newton-Cartan (TSNC) sigma models those are defined over non-Lorentzian
manifolds. We further show that under transverse T-duality, these TSNC sigma
models are mapped into another new class of nonrelativistic sigma models those
are defined over a T-dual TSNC background. Considering nonrelativistic limits
of various field theory observables in a holographic set up, we further
estimate corresponding entities in the TSNC limit of $ \mathcal{N}=1 $ quivers.
We carry out a parallel analysis on holomorphic functions and the associated
pole structures in the nonrelativistic limit of ($ p ,q $) five brane webs. In
particular, we investigate the generic structure of various loop operators in a
nonrelativistic set up and explore their properties under S-duality. Finally,
we comment on the large $ c $ limit of RR fields and discuss the associated
S-duality transformation rules in the nonrelativistic limit of $ \mathcal{N}=1
$ quivers.
