It's a great route, however my personal thoughts on all DLC is best to wait till it's on sale. Often some great savings to be made, and it stacks up when you're trying to build out a collection. Could allow you to buy like 2 DLC rather than 1 with the same amount of funds, for example.
If you already have most of the layers, I'd say it's worth it. Although the HST runs are a bit short. I'd recommend it purely because it's one of the few diesel routes we have, but with only the HST and 158 it's not really worth it.
LucaZone Adam, what are your thoughts on adding a mild implementation of exhaust emissions, using the Just Trains exhaust setup, on the MML HST ?
Just a quick little bug I've noticed following the recent update; the AI don't set the head or tail lights on the HST anymore for some reason, and even when the player is driving - the taillights are still not on for the rear powercar and need to be turned on by the player. Very small issue but seeing trains running with no head or tail lights on is a pet peeve of mine, as I have recently discovered...
Not sure if this is new or has been around for a while, but some of the safety system isolation buttons are either mislabelled or linked to the wrong thing. DSD Isolation actually controls the Vigilance, and Vigilance Isolation actually controls AWS. There doesn't seem to be any way to turn DSD on Another minor thing is that if Automatic Coupling in the player assist menu is turned on and you couple two power cars together nose to nose, the coupling bar does not appear and they are only connected with air hoses This meanwhile isn't a bug, but if Skyhook consider making the guard panels on the Mk3 coaches functional and allow us to access the guard compartment on the 'A' coach, and the back of the power car, that would be cool
