We construct black string solutions in Type IIA supergravity arising from intersecting D2-D4-D6-NS5 branes in the presence of fractional D4-branes. The fractional D4-branes arise from D6-branes wrapping (collapsing) two-cycles in a Calabi--Yau two-fold. In the near horizon limit these solutions give rise to AdS$_3$ geometries preserving $\mathcal{N}=(0,4)$ supersymmetry and fall within the recent classification of \cite{Lozano:2019emq}. We interpret our solutions as describing chains of black strings stacked on top of each other along an interval. We construct 2d quiver CFTs dual to our solutions that reproduce the Bekenstein-Hawking entropy microscopically.
