The Most Rewarding Route

I am deciding to buy, is there any worthwhile route to buy?

 

What do you mean by most rewarding? The one that poses a good "challenge"?

 

They all have value. It depends on your interests, passenger or freight, commuter or long distance, country/region, era, traction etc. I assume you started with an initial bundle.

 

Both TSW2 and TSW2020 bundles offer a good price for multiple routes.
