  We study theoretically the nature of correlations in space and time of the
current in a one-dimensional bilinear array of tunnel junctions in the normal
conduction limit, using the kinetic Monte Carlo (KMC) method. The bilinear
array consists of two parallel rows of tunnel junctions, capacitively coupled
in a ladder configuration. The electrostatic potential landscape and the
charge-charge interaction length both depend on the circuit capacitances, which
in turn influence transport and charge correlations in the array. We observe
the formation of stationary charge states when only one rail is voltage biased.
When a symmetric bias is applied to both rails, the site at which the positive
and negative charge carriers recombine can drift throughout the array. We also
calculate charge densities and auto- and cross-correlation functions.
