Do you mean Bahnstrecke Salzburg – Rosenheim? Unfortunately, no more information has come out since then. But I would still imagine that the currently unnamed depots are for LIRR2 & Gospel Oak-Barking Riverside and that Salzburg-Rosenheim's depot/download size isn't in the steamdb yet (then again, I could be wrong).
So to my surprise, depot 2584130 was in the end for Bahnstrecke Salzburg - Rosenheim, coming out tomorrow. Final download size for that one will seemingly be 6.34 GiB. But in more exciting news, an update today has brought two new unnamed depots with download sizes into the steamdb, and they are quite large. The larger depot is 2584120 with a size of 7.84 GiB, in-between Cajon Pass & East Coast Main Line's download sizes. The other depot, numbered 2662100, is sized 6.58 GiB, the same size as Tharandter Rampe. The former is definitely for the unannounced/delayed LIRR 2.0 route, the later is probably for Semmeringbahn, as that is said to be the next route after Salzburg-Rosenheim & the GOBLIN.

How to know what the codes in the steamDB relate to? Since the LIRR M3 is being updated, hopefully we receive news about the new LIRR on this Tuesday's roadmap
You note the AppID of the DLC. Its depot id will be the same as the app id - for content updates changes done in depots are what matters. For updates done not in the public branches, you need to check the update history of Train Sim World 4 app and not directly of the given depot. The AppID/depot of LIRR M3 for TSW4 is 2375902. Along with the same development update, additionally to LIRR M3 depots of also GWE, Peak Forest, MML & 5 other encrypted DLCs were touched.
A little birdie told me that MML is getting another update alongside the release of Cargo Line 2, expect Mountsorrel to be updated, AI timings to be fixed and the 158 doors to close quicker
And hopefully fix the gauges they broke in the last patch (HST needles invisible at night, 158 dials freezing in snow).
A small update for today, 6th March: Depot 2584120 was updated 10 hours ago: https://steamdb.info/depot/2584120/ Depot 2662100 remains last updated 26th February: https://steamdb.info/depot/2662100/ Depot 2584140 was also updated 10 hours ago: https://steamdb.info/depot/2584140/ Sadly, I think none of the depots are LIRR 2.0 (unless there are strong pointers to one of them being it that I missed?). It's most likely that it's Goblin / Suffragette, then Fife Circle Line followed by Semmeringbahn. My guess would be the ~ 5Gb depot 2584140 being Goblin / Suffragette, and the nearly 8Gb depot 2584120 being Fife Circle Line.
At the end of the roadmap they were dropping some big hints more information is just about to be released.... maybe a few weeks... or by end of March. They said watch for announcements.
I don't believe that's the case. Just watch when next Roadmap comes around or a few weeks time or hell even a days time it STILL won't be announced. If the "unannounced" American Route is announced in the next few weeks or BY next Roadmap I will personally delete my account on the forums. But until they announce it I'll be a monkey's uncle
Yep, depot 2662100 is for Fife Circle Line, which in a way, makes sense considering the nature of that route and of course, the Forth Bridge. I already said that depot 2584120 is mostly likely LIRR 2.0 and 2584140 is guaranteed to be GOBLIN/Suffragette.
some DLC was updated on SteamDB today on the rc_preview branch which is the last stage before a patch goes live, the M3 and Salzburg are a part of it as well as 3 unknown route DLC's which I guess would be Goblin, Fife Circle and LIRR 2
Today's updated brought anew unnamed depot with download size into the steamdb, numbered 2662130 and sized at 6.18 GiB, in-between the sizes for Linke Rheinstrecke & NEC: New York - Trenton. If recent releases are anything to go by, this has to be the depot for Semmeringbahn, because I don't know what else it could be for.
