Heya, back again
I think i have discovered a couple more bugs in the set (im not sure).
The first new one has to do with the E8 diesel livery override for passenger cars. For the yellow override it works fine, but when the E8 changes livery to the Amtrak silver/blue/red, current E8's running do as well. This is great, however the passenger & mail coaches revert back to their original livery, ie: the brown or silver carriages. It seems that the Amtrak E8 doesn't have a livery override, as the coaches available in the new vehicles window also change livery to match the Amtrak colours. The problem is with the pre-amtrak livery coaches that are currently in service to the yellow E8's are not being overridden to look similar when the E8 heading the train changes livery from yellow to Amtrak. Screenie attached.
The second thing i noticed was regarding reliability after servicing. Usually (in ttdlx vanilla & the other graphic sets) reliability decreases normally until the train is 1 year older
than its max. age (21/20 years old etc "... is getting very old & urgently needs replacing") then its reliability after servicing drops 1% every couple of seconds, hence the 'urgently needs replacing'. With the USSet I noticed that the instant that the engine hits its final year of service (from 19/20 to 20/20 years etc; "... is getting very old") its reliability diminishes as if it were 'urgently needing replacement'. This kinda makes the engine less useful in its final year, effectively making its life span 1 year lower than the 'advertised' lifespan, as you have to replace it as soon as you can after you get the 'its 20/20' message; unless, of course you can put up with traffic jams caused by the frequent breakdowns of the old, but not yet too old, loco. Not sure about most people, but I usually wait until i get the 21/20 message (urgently needs replacing) where the train actually does need replacing or it will hinder company performance before I replace my engines; and as force of habit i'll probably keep doing that, unwittingly causing myself major traffic & economic headaches. As far as i can tell it isn't specific to 1 train, as all the different engines I've checked since i noticed this have behaved in the same way.
Is this a bug?
I'm really enjoying this set, and am currently in 1972. Its great so far. Especially how each engine is useful in its own way.
