On these pages you will find some information on Transport Tycoon Deluxe and the possible enhancements and extensions provided by TTDPatch and OpenTTD. Both introduce various rather complex new features, therefore I have written some guides about building realistic railway networks.

Highlights include:

railway networks for dummies

path based signalling for dummies

realism guide for Michael Blunck's DBSetXL

information about the GermanRV set

Since TTDPatch and OpenTTD have implemented various features quite differently, you can set a filter for these pages, so that you will only see building variants and explanations that are actually available in your game: Show only TTDPatch or OpenTTD.
