The Big Boy is good!
Challenger? Alot of wheelslips but I managed. Man am I dumb

, I've looked into 2 units and always thought the Challenger is the same 4-8-8-4 only smaller. When I test it on Donner Pass last week I was like... "Wait a min! That has 3 not 4.
Reason why we needed the performance because it wasted the steam so quickly the fireman was having a hard time trying to keep up with the steam pressure on Cajon Pass, even the GTrax Steam. I switched it to manual fireman trying to figure it out myself. nothin. I could not figure out what in the world I need to do to drive this steam engine. I love it so much but it's not giving what I wanted. So I stopped driving steam for like 8 months only to drive it on a flat grade feeling bad about the simualtor. Now with the performance its all good and the new HUD I can now enjoy driving steam and fell in love all over again. That's just me
The trick to drive that Cab Forward is to use the Coal and Water Icon. Also Blower! They perform great!
Did you know?
RSC did something about how Coal and Water Icon works? I looked over the driving manual and here's what I figure it out.
Steam Overlay how it works:
IN ORDER: (overlay On)
1st What works:
Cylinder ** "C"
Small Ejector "J"
Firebox Icon:
Firebox "F"
Rate Shovelling Coal "R" (high)
Water Icon:
On/Off Live Injector "I"
Flow to Live Injector "K"(high)
What doesn't work
Exhaust Injector "O"
Flow to Exhaust Injector "L"
2nd What works
Increase/Reduce On/Off Blower "N"
Increase/Reduce On/Off Damper "M"
I put these in order so it won't confuse me. The Water and the Coal both work together. Thats what you need to concetrate those to for the cabforward. Don't let the water go below 80% and the fire below 70%. Give it a try. The more you build up steam the more power you get. Also drop the Regulator and the Reverser to get more power if you need to on those climb.
