📋 About This Mod
RLW PRR M1a & PRR M1b Mixed use Locomotive
IF YOU ARE UPDATING THIS MOD FROM THE OLDER VERSION YOU WILL NEED TO FIND AND DELETE THE FILES CALLED "RLW RXM-1B CLASS" and "RLW RXM-1 CLASS"
This mod adds 4 versions of the PRR M1 4-8-2 Mountain mixed use Locomotives to railroader
The four versions of the PRR M1 are split up into 2 types, the M1a and the M1b what has slightly different stats. Both versions share 2 different tenders a coast to coast tender and a 130-p-75 tender what replaces the old 110-p-75 tender the V1 of this mod had
The 4 PRR M1 will show up as, PRR M1-a, PRR M1-a (130-P-75), PRR M1-b and PRR M1-b (130-p-75) in the buy menu and the prices are different for each version of the M1. The M1-a is $28,000 where as the 130-P-75 tender version is $26,000. The M1-b is $33,000 and the 130-P-75 version is $30,000
The M1-A has a tractive effort is 64,500 with a FOA of 4. 2.
And The M1-B, has a tractive effort is 69,700 with a FOA of 3. 9.
My versions of the Pennsylvania Railroad M1s are close to their real world basis but with some slight changes mainly to the cab layout.
The locomotives have 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 M1s have the option of a toggleable PRR Keystone instead of the standard front numberplate.
The PRR M1-b's have a post war cast pilot with a fake but "useable" flip out knuckle
