Thank you for your interest in expanding RailServe.com's Microsoft Train Simulator Add-ons Site. Please select up to three (3) files using the fields below and click "Upload!" to send them to RailServe.com. It is recommended that you send text files and multi-file components (such as add-on locomotives and activities) in ZIP files, being sure to include a text file clearly displaying the developer's name, a description of the item, and installation instructions.

Add-ons that are accepted for addition to RailServe.com will usually be added to the directory within one week. Note that RailServe.com reserves the right to reject submitted files for any reason. Proper credit to the author is always provided next to each listing.

NOTE: If you have your own web site that hosts your MSTS add-ons, DO NOT submit your files using this form. Instead, please contact RailServe.com with the address so that a link for each of your add-ons can be established at RailServe.com. Unless specifically requested, RailServe.com will link to the web page you provide, NOT directly to the file.

Please press the following button ONE time only. It may take several minutes or longer to upload the requested files depending on the size of the files and speed of your Internet connection. If your web browser times out while uploading, please return to this page and upload files individually, or contact RailServe.com for assistance.
