I need advice on building an 027 model railway, it needs to have shunting yards, big train station (4 track station), refuel stations, custom built sheds for 3 engines, rolling stock shed (passenger cars only), and ballast around the track. Pretty much a full blown railway. Also I'm just starting so thats why i need help with this, and yes I'm aware this will take a long time to do based on how I'm describing it. So I'd appreciate some help because I know that barely anyone has attempted this so this is going to have trial and error for me and my dad if he's wanting to do this. And I do have a nice marx 490 locomotive and set, so there's my start.
