📋 About This Mod
RLW PRR K4 & PRR K4 "Cast Pilot" Passenger Locomotive
IF YOU ARE UPDATING THIS MOD FROM THE OLDER VERSION YOU WILL NEED TO FIND AND DELETE THE FILES CALLED "RLW RSP-1B CLASS" and "RLW RSP-1 CLASS"
This mod adds 4 versions of the PRR K4 4-6-2 Pacific Passenger Locomotives to railroader
The four versions of the PRR K4 are the same in terms of stats, the differences are that one version has a PRR post war cast pilot and both versions have 2 tender options, a 110-p-75 tender and a 130-p-75 tender
The 4 PRR K4s will show up as, PRR K4 (Cast Pilot), PRR K4 (Cast Pilot 130-P-75) PRR K4 and PRR K4 (130-p-75) in the buy menu and they are both default versions are listed for $21,000 where as the 130-P-75 tenders are listed for $23,000
My versions of the Pennsylvania Railroad K4 are close to their real world basis but with some slight changes mainly to the cab layout.
The Four PRR K4s share the same stats of that of a real PRR K4, these being
The tractive effort is 44,700 with a FOA of 4. 7. The Tenders on the RSP-1s are 110P75s also of the PRR,
the fuel load is 21. 8t of coal and 11,300 gal of water
The locomotive has a paintable body, Keystone Backing, Cab, Cab Roof, Cab Roof 2, Cylinders, Cylinders Trim, Cylinder Inner Trim, Inner Trim, Trim, Cab Trim, Cab Inner Trim, Runningboard Trim, Window Frame, Cab walls, Handrails, Numberplate, Pilot Trim, Wheel Trim, Wheel Trim 2, Wheel Trim 3 and Pilot that will help in making each locomotive unique to everyone's personal railroads.
There is 3 default liveries being, RLW Green, RLW Blue and PRR style
The PRR K4 have the option of a toggleable PRR Keystone instead of the standard front numberplate.
The PRR K4 "Cast Pilot" has a post war cast pilot with a fake but "useable" flip out knuckle
