DB1: Optional tiles - A #887 tile has promoted the hexag south-west of London, as an alternative to the #14 and #15 tiles.  A #205 tile has been laid in Oswestry.  Elsewhere, #887 and #888 tiles have been used in lieu of the #87 and #88 that come with the basic game (the new tiles are value 20 instead of 10).  An extra #38 tile has also been laid.

DB2: SECR Changes - The hexag to the south-east of London was reserved for the SECR.  It took advantage of this to constrain the routes available to the LSWR and LBSC, at the cost of slower tile development for the SECR itself.

DB4: Ferry markers - In this game we used my older, simple rule that increases the value of the named ports on the board by 10.  (The more recent version of the rule requires a company to place a marker in order to get this bonus).

DB6: Extra minor companies - The MMR developed the South Welsh coast line, which you can see coming into Cardiff.  The SDTR was placed in Devon, outside the area in the photo.

DB8: Alternative trains for minor companies - The alternative trains for the MGNR, TVR, MMR and SDTR encouraged the development of regional track, aided by my house rule that in phase three, a company may lay yellow tiles in adjacent hexes.  The addition of Hereford encouraged the Cambrian to develop a profitable U3 route along the Welsh border.
