Once you have made a consist and saved it, it will be there for you to place on any of your routes. When you are in Surveyor, and are placing rolling stock and locomotives on the track using the TRAINS button, after you have made up your consist, then click on the consist button at the top of the train tab window. Next, go down to the button on the bottom left in that tab that shows "Get Consist" when you hover your mouse arrow over it and click on it. Then, go back to the Surveyor, click on your new consist, the window will pop up saying "New Consist" but simply back space over that or highlight it and just write in a unique name for your consist. Click save, and you have your consist for any route you wish
Names I might use: UP Big Boy Passenger Consist Long for a passenger consist of perhaps 10-15 Pullman type cars behind the UP Big Boy and Tender. Or something like CSX 3 SD40 Coal Consist 36 Gond to describe a 3 engined CSX consist of SD40's with 36 gondola cars. Have fun!
