RailMaster was unleashed upon the public and model railway enthusiasts in 2011 but there is an extension to the software in the name of the RailMaster Pro Pack. This is an add-on to the standard version of RailMaster and incorporates many added features which are well worth the upgrade if you are enthustiastic about DCC operation of your layout via the eLink or Elite.
I have taken the list of features on this page from the official release .pdf file and by no means is it exhaustive. There are many more features and more will be added as time moves on no doubt.
Purchasing the Pro Pack is a simple task and can be done instantly within RailMaster itself. The current price is £29.99 and once it has been purchased you are sent an activation code within 48 hours (although it is usually extremely quick) for you to be able to get started.
