Hey folks,
As I'm sure many of you know, the DLR has something of a unique third rail system with lightweight, small cross section bottom contact power rails rather than the traditional NR/Tube heavy top contact third rail.
Was wondering, does this arrangement completely preclude the possibility of ever running mixed services on the same track? I'm imagining that the DLR trains might foul a normal third rail, and vice versa, but I'm not sure, there might just be room?
Are there also additional loading gauge constraints on the DLR that would stop a normal sized NR stock from running on its lines?
I know it's unlikely we'd ever see this for real, but just a thought experiment really, also looking for further details on the DLR's system and whether it's used anywhere else.
