Nor whatever additional tracks and revised junctions are eventually settled on for a Leicester area remodelling. Getting track changes and compatible signalling finished first before starting work on erecting stanchions and wires is essential for cost control and value. Bi-modes are a pragmatic solution to the delay before all these elements can be completed, or there is sufficient wiring present to allow the diesel gen-sets on the trains to be replaced by battery packs. The Derby and Nottingham areas are already remodelled, resignalled and compatible with future electrification, so perhaps an isolated island of electrification might be considered in that area that could be of some use to bi-modes in extending range and reducing pollution in urban areas. On the other hand it might be more prudent to wait until after HS2 enabling works are decided on and finished around there, as there must be some significant changes to the classic network required around Trent and Toton.
