This thesis presents an analysis of neutrino interactions using the Electromagnetic Calorimeters (ECals) of the Tokai-to-Kamioka (T2K) off-axis near detector (ND280) as a target using data collected during T2K run 3C. The analysis presented shows the development of a new set of re- construction algorithms which are able to reconstruct multiple tracks which originate from the same neutrino interaction. The output of this reconstruction is used as the basis of a νμ charged current inclusive selection in the ND280 ECals. The selected events are then used in a simple X2 fit to extract a T2K flux-averaged νμ charged current inclusive cross-section on lead, which is measured as (σCC)ψ = 8.13+1.33 x 10⁻³⁹ cm2 nucleon-1.
