Station promotions - These variants modify the promotion paths for certain types of stations.  The first set, which I designed, reduce the bottleneck caused by demand for the green tiles nos. 14 & 15 (generally known as 'X' and 'K' tiles).  Another variant, by Ronald Novicky, replaces the reasonably freeform nature of the original game with more clearly defined promotion paths.

Ferry variants - These variants add rules for the coastal cities marked as bases for "steam packet" ferries. These cities are named in white capital letters on the map. The variants encourage the building of track to these cities, giving more options to game play.

Single track tiles - The regional kits for Norfolk and Wales originally included single-track tiles, which could only be laid and used by ‘3T’ or ‘4T’ trains. The original rules for single-track tiles had some problems, so those kits were replaced with new versions that just used ordinary track tiles.  This variant, by Mike Hutton, adds these tiles back into the game. 

Variant kits - I also provide kits of optional tiles, single-track tiles, share certificates and changes to the board.  This photo shows the result of a game that used several of these kits with Unit 1 and the three regional kits.

• Kit DB1 contains new tiles that provide more options when promoting stations. It can be used on its own or with my station promotion variant.

• Kit DB2 makes minor adjustments to the SECR in Unit 1 to improve game balance.

• Kit DB3 consists of several small changes to the Unit 3 board in an attempt to make the historical routes more likely to be chosen during game play.

• Kit DB4 gives some simple markers for use with my variant for ferries.

• Kit DB5 provides tiles and share certificates for use with the single-track variant.

• Kit DB6 comprises charters and share certificates for extra minor companies.

• Kit DB7 offers some alternative grey track tiles.

• Kit DB8 provides alternative trains for some of the minor companies, with the primary intention of encouraging track development in less developed areas of the board.

Metropolitian railway - This variant, by Geoff C, adds a minor company running from central London.

Other variants - The first section lists variations that some other players use and that I have not adopted.   The second section lists some possibilities that I have yet to try.
