It's not always possible to add branch lines. Some end up being too long or you would have to shorten the mainline to add more branch lines in which means you might get 2 odd endpoints or you would need to add more locos. Game development is time consuming and
Then take a bit more time now they have 3rd party devs chipping in. I'm not asking for 30 mile long branch lines. Just ones that make sense. A few miles to give more variety
The mml route which is upcoming has both the lines to Nottingham and Derby and BCC has the Redditch branch.
That's the exception not the rule. I'm wanting more as the routes that have them are the best ones imo. BTW, the line to Derby isn't a branch line, it's a mainline route. One that should go upto Sheffield, but that's another topic
No the branch on this route would be the line to Nottingham. I am not disagreeing but just saying branches have been/are being done.
