📋 About This Mod

Adds in a Freelance Streamlined diesel Locomotive and its b unit.

RLW SP1 & SPB

This mod adds a freelance Diesel locomotive to Railroader

The SP1 will show up as "RLW SP1" in the buy menu and is listed for $30k

The SPB will show up as "RLW SP Booster Unit" in the buy menu and is listed for $28k

CURRENTLY NOT FULLY COMPATIBLE WITH THE 3. 0 PASSENGER CARS

The SP1 & SPB are loosely based on the Alco PA locomotive and its booster unit. The starting tractive effort of both the SP1 and SPB is 61,000 with a FOA of 4. 8, Both units have a capacity of 1200 gal of Diesel fuel

Both the SP1 & SPB have a paintable body, 2 side stripes to match and line up with my streamlined passengers cars, along with paintable skirts. The SP1 and SPB come with 5 default liveries, RLW Blue. RLW Green, PRR Style, PRR Style 2 And D&H Style.

The SP1 & SPB have a modeled interior, though its not the most detailed or accurate. The SP1 has a fully modeled cab that can be accessed via the front most doors on the body of the locomotive or the rear doors of the cab found within the body of the SP1 it self. The Cabs controls are fully functional.

2. 5. 0 Update

The 2. 5. 0 update adds a range of new details and fixes. A set of Trainphones as been added as a detail model that can be turned on and off to give your locomotive that extra bit of flair, I've also decided to trail having the roof of the locomotives be a paintable part now. 3 new default liveries have been added, 2 inspired by PRR designs and 1 inspired by the D&H.

The headlight setup on the front of the locomotive has been reworked and updated to now have a lower main headlight and in the spot of the old headlight is a Mars light what does work, The mars light is activated via a brand new toggle switch in the cab. While on the subject of the Cab it also had a update, chairs have been moved backwards, controls have been reworked to be more useable in 1st person and no longer get stuck in place. A Horn lever has now been added to allow for use of the horn from the cab.

Wing mirrors, a Fuel port, upper "chrome" roof trim, clearer prime mover name plate, and moving cab windows have been added also in the 2. 5. 0 update.

I've also added a set of "Fake" Knuckles to the locomotive so i could add a front knuckle door cover to improve the look of the locomotive. These Fake knuckles wont animate when ya attach stuff to them but they can be clicked to unhook cars and other locomotives.

And Finally I've made it so the fans on both the SP1 and SPB roofs spin on a loop when the fan is clicked, in the future id like this to be linked somehow to the locomotives speed and engine but for now this will have to do.
