I have 75 GB on my Railworks dedicated drive and it only takes about 20 seconds to get to the drive menu. Hopefully your new laptop has a spot for a good M.2 drive to store your Railworks folder on and a fast SSD with a good cache size.
Actually, everything should work, as I do not have any third party content installed yet; hence no dependency requirements ..the entire "new" installation is straight off the Steam shelf. Next will come the arduous task of installing all the non-Steam content; but very selectively. For example, there are some routes that are otherwise nice, but come with some less than desirable assets that get installed in the process, and my original installation is cluttered with them. So this time around, rather than drag a bunch of pre-installed folders from my old install onto the new one; I'm going to install fresh out of the zip files. The only exception might be for loco and rolling stock repaints that require plucking the Geo-files from ap-files and such.
@ Trev: Thanks, that's what I was hoping to hear originally, but found out for myself as described below.
Anyways; the new laptop arrived: Acer Nitro 17 Gaming Laptop (17.3" QHD 165Hz @ 2560x1440, AMD 8-Core Ryzen 7 7840HS, 64GB DDR5, 2TB M.2 SSD, GeForce RTX 4060 8GB).
I'm happy to report that everything went well with the new installation. I did not make any changes to the existing installation before doing the setup on the new laptop, other than logging out of Steam. Here's what I did, step by step:
1. Started the laptop, logged into email so I could receive my Steam verification code once the time came. Installed Steam onto the new laptop, logged in and entered the code sent to email.
2. Went to my Library and observed all my games being present but not installed. Went to TS Classic and selected "manage my ### dlc" and saw that all my dlc had the boxes checked, ready for installation; this is apparently the default, as there were a few on my original installation that were unchecked. Going through my dlc list, I unselected everything I did not want on my new installation.
3. Returned to the game icon and selected "Install" and specified the location at the prompt; my laptop came with a 2TB ssd, partitioned in half for a C and D drive; I installed onto the D drive. A few hours and 149GB later, the installation was complete, and I did a "file verification" just to be sure everything installed without error.
Lastly, I needed to check my old rig to see if unchecking the dlc on the new rig had any effect on the original installation. I logged out of Steam on the laptop and logged into Steam on the original rig. Then went to TS Classic "manage my dlc" and all the original checked boxes remained just the same as when I started.
So, to answer my own question: Yes, you can do a streamlined installation on a new pc using the same user account without affecting a much larger installation on an existing pc. Just be careful to uncheck whatever dlc you don't want on the new rig before clicking the "install" button for the base game.
I hope this will relieve any doubts for anyone considering the same process. Thanks again to those who responded and tried to help
