  Raghunathan at al. [9] introduced splitting operation with respect to a pair
of element for binary matroid and characterized Eulerian binary matroids using
it. In general, the splitting operation does not preserve the graphicness
property of the given matroids. Shikare and Waphare [10] obtained the
characterization for the class of graphic matroids which yield graphic matroids
under the splitting operation with respect to a pair of elements. We study the
effect of the splitting operation on regular matroids and characterize the
class of regular matroids which yield graphic matroids under the splitting
operation. We also provide an alternate and short proof to two of the known
results.
