OpenRoads or OpenRail?

Hello Everyone,

My company is about to buy one of the Bentley products and they asked me to learn which one is better for my work. So I've search for the right product but I still have questions and I would be appreciated if you can help.

I am using PowerCivil SS2 and InRoads right now and I want to use the new product in the same way. Actually as far as I've searched, I saw that OpenRoads is similar to InRoads. But my company wants to learn if OpenRail covers all the features in OpenRoads. So we can buy Openrail and use the Openroads and rail features in the same time if needed. So I need your suggestions.

Thank you in advance.
