 If completed, the GCRN would merge with the GCR to create a single track which would also be rebuilt as a double-track line for most, if not the whole, of its length.Latest engineering studies of 'the Gap' have produced a design for a single-track link (difficult to justify the additional cost for double-track) - previously proposing to utilize two, ex-Network Rail, single-track bridges (removed as part of the Reading Station upgrade), now to be utilized to bridge the Preci-Spark Car Park and Railway Terrace.The latest design proposes to re-instate the bridge over the Midland Main Line utilizing a new-build single span bridge, complying with electrification clearances for the recently announced electrification project.
