A 20 metre section of viaduct with attached track and central brick pier only, to enable two lengths of DDD HL viaduct 01 (spline) to be joined when ends with brick piers would otherwise meet. To attach a viaduct spline, use 'grey conc clean std ...' track, (TS2010 built-in). As an alternative, 'DDD HL viaduct 02' could be used for this.
