S282

The S282 is one of two operable steam locomotives in the game, the other being the S060. It is comparable to the DE6 locomotive in terms of load rating and is generally cheaper to run, but at a cost of higher workload during operation. It requires obtaining a proper license before operation is allowed.

## The Locomotive

The locomotive is driven by high-pressure steam at a maximum of approximately 14 bar (203 PSI), generated from heating water in the boiler by burning coal in the locomotive's firebox. The locomotive has a 2-8-2 wheel configuration, with 2 leading wheels, 8 coupled driving wheels and 2 trailing wheels under the cab supporting the weight of the cab and firebox, hence the '282' in its name. The locomotive holds 600 units of sand.

## The Tender

The locomotive is operated coupled to a tender, which holds main stock of coal and water. The coal is shovelled from the tender into the locomotive's firebox, and water is added to the locomotive's boiler by operation of a injector valve in the cab. The tender holds 20,000 units of water and 10,000 units of coal.

The tender's water level can be checked by climbing on top and opening the water filler hatch towards the rear. The remaining water can be viewed through the hatch. The remaining coal amount is directly visible while on top of the tender.

***(93+)*** The tender, like all other rolling stock in-game, has a handbrake, which can be found on the tender footplate.

If the tender should become uncoupled from the locomotive, it can be recoupled by reversing the locomotive into the tender however, the S282 is unable to maintain brake pressure without the tender.

## Controls and Instruments

### Reverser

The reverser (also known as the cut-off handle) controls the direction and power ratio of the locomotive. It is located below and to the right of the driver's window, and is easily identified by its red wheel-like manipulator. To the right of this red manipulator is a scale plate and a needle showing the current reverser setting.

The reverser selects the power-to-speed ratio of the cylinders, by changing the timing of introduction of steam into the cylinder along the piston's stroke. The action of the reverser is achieved through a Walschaerts Valve Gear mechanism on each side of the locomotive.

When the reverser is rolled fully forwards, full power ahead is achieved, by letting steam into the cylinder for almost the entire piston stroke. Then as the reverser is rolled towards the middle, more speed is achieved by only allowing steam to enter the cylinder at shorter distance of the piston stroke.

When the reverser is in the exact middle position, power output goes to zero, as no steam is let into the cylinder at all.

The reverser may also be rolled fully backwards for full reverse power. Then, similarly, as the reverser is rolled towards the middle, more speed is achieved.

(As of Build 93, the reverser effects the efficiency instead of speed)

### Regulator

The regulator is located above the firebox doors, as a long handle pointing out and towards the driver of the locomotive. The regulator dictates how much steam is being directed into the cylinders.

***(92-)*** Pushing the regulator forward increases throttle, and pulling it backward decreases throttle.

***(93+)*** pulling the regulator backward increases throttle, and Pushing it forward decreases throttle.

### Water Gauge

The water gauge in the cab measures the water in the boiler, although it does not measure the capacity of the boiler in its entirety, but rather a smaller range of it. I.e. when the water level is at the bottom of the gauge, this does not necessarily mean that the boiler is empty.

***(92-)*** The in-game manuals state that the gauge reads the range from 75% to 85% of the boiler level. However the actual reading is closer to a range from 67.5% to 82.5%. This corresponds to the gauge measuring 3,000 units of water, from 13,500 units at the bottom to 16,500 units at the top. The effects of overfilling the boiler (priming) or running dry (activated fusible plug and boiler explosion) are currently not simulated.

***(93+)*** The water gauge is only accurate when on level track, & it varies drastically when the locomotive is on a gradient, due to water sloshing around in the boiler. overfilling the boiler (priming) or running dry (activated fusible plug and boiler explosion) are simulated, although boiler explosions may happen for other reasons than running dry. (A severe derailment can also cause a boiler explosion for example)

### Whistle

The whistle is located above the reverser, as a brown rope. Pulling the rope creates a sound signal by letting steam flow through the whistle on the boiler. The further the rope is pulled down, the higher the tone gets.

### Valves & levers

***(92-)*** The locomotive has five red valves located to the left of the regulator. Underneath the four functional ones rest nameplates with their function engraved on them.

***(93+)*** The locomotive has three red valves located to the left of the regulator, along with the controls for the headlamp, rear headlamp, & gear light. Three other valves for the Dynamo, Air pump, & lubricator are on the engine itself.

#### Valves & levers on the S282 As of & before build 92:

##### Water Dump

The first valve from left to right is the water dump valve. When rotated, water will exit the boiler, thus lowering water level in the water gauge. The speed of the water can be adjusted, depending on how far the valve is turned.

##### Steam Dump

The second valve is the steam dump valve. Upon rotation, steam will exit the boiler, lowering steam pressure. Just like the water dump valve, the speed of steam leaving can be adjusted by opening the valve more.

##### Blower

The blower is the lower valve. Located underneath the fourth (non-functional) valve, the blower can be used to boost the fire. This is done using steam pressure. Turning the blower further  uses more steam and a hotter fire uses more coal.

##### Fire Out

As the name suggests, the fifth valve makes the fire go out. The fire out valve is located to the far-right of all the valves and sits at an angle. The valve can not be used at high temperatures: the fire will only extinguish at ~150°C or below and when the coal level in the firebox is low.

##### Brakes

The locomotive is equipped with two brakes: the independent brake and the train brake. These are located directly to the right of the firebox, with the independent brake more to the front of the cab. The independent brake is used to slow down the locomotive. The train brake is used to slow down the train and all the wagons connected with brake pipes. The brakes use steam pressure, though the train brake uses significantly more than the independent brake. The brake pressure can be read from the pressure gauges, with each brake having its own gauge. If the train brake has not yet fully built up pressure, the train will accelerate very slowly. This can be remedied by opening the regulator further. Opening a brake valve of the locomotive or a connected wagon also activates the train brake.

##### Injector

The injector is located above the valves and used to let water enter the boiler. Turning the injector valve further increases water flow speed.

##### Sander

The sander is located to the right of the fire doors. It is used to deploy sand on the driving wheels of the locomotive. This gives the wheels more grip, allowing the train to accelerate faster on flat ground and steep hills. The sander is especially useful when carrying heavy trains or climbing steep mountains. The sander has its own gauge underneath it, reaching from 0 to 1.2 m3.

##### Fire Doors

The fire doors are in the middle of the cab, underneath the regulator, as a stick pointing to the right side of the cab. It is used for access to the firebox. It can be opened and closed.

##### Damper

The damper is located underneath the brakes, depicted as a stick with a 90° curve pointing towards the tender. The damper has the same purpose as the blower, to boost the fire, but the damper doesn’t run on steam. The damper is used while driving. Using the airflow from the moving of the train, air gets directed into the firebox. The damper has five positions, where completely up is off and completely down means fully on.

#### Valves & levers on the S282 as of & After build 93:

##### Blowdown

The first valve from left to right is the water dump valve. When rotated, water will exit the boiler, thus lowering water level in the water gauge. The speed of the water can be adjusted, depending on how far the valve is turned.

##### Bell

The second valve is the Bell. Upon rotation, steam will start to ring the bell.

##### Blower

The third valve is the Blower. The blower can be used to boost the fire. This is done using steam pressure. Turning the blower further  uses more steam and a hotter fire uses more coal. It is recommended that it only be used when the engine is stationary.

##### Coal dump

Replacing the "fire out" valve on the the S282, the coal dump is a lever to the left of the firebox doors that dumps coal that is currently in the firebox.

##### Brakes

The locomotive is equipped with two brakes: the independent brake and the train brake. These are located directly to the right of the firebox, with the independent brake more to the front of the cab. The independent brake is used to slow down the locomotive. The train brake is used to slow down the train and all the wagons connected with brake pipes. The train brake on the S282 is a "Non self-lapping" brake, which the DM3 also has. It has 3 positions: release, lap, and apply. Release releases brake pressure, apply adds brake pressure, and lap holds the brake pressure at the point the brake pressure was when the lever was put into lap.

##### Injector

The injector is located above the valves and used to let water enter the boiler. Turning the injector valve further increases water flow speed. Injecting water cools the boiler, so when injecting water, less steam is generated.

##### Sander

The sander is located to the right of the fire doors. It is used to deploy sand on the driving wheels of the locomotive. This gives the wheels more grip, allowing the train to accelerate faster on flat ground and steep hills. The sander is especially useful when carrying heavy trains or climbing steep mountains. The sander has its own gauge underneath it. In builds 93 & 94 the gauge has no unit of measurement & no numbers.

##### Fire Doors

The fire doors are in the middle of the cab, underneath the regulator, as a stick pointing to the right side of the cab. It is used for access to the firebox. It can be opened and closed.

##### Damper

The damper is located underneath the brakes, depicted as a stick with a 90° curve pointing towards the tender. The damper has the same purpose as the blower, to boost or cool the fire, but the damper doesn’t run on steam. The damper is used while driving. Using the airflow from the moving of the train, the damper allows the fire's temperature to be controlled, as to not burn excess coal.

##### Cylinder Cocks

The Cylinder cock lever is on the right side of the cab, directly next to the train brake. It allows water to leave the cylinders, which is important, since water can't be compressed like steam. Not operating the cylinder cocks upon startup can damage the cylinders. A sloshing sound with play when water is in the cylinders.

##### Dynamo

The Dynamo uses steam to generate electricity to power the headlamp and lights. It's valve can be found on the top of the boiler. When on, a Buzzing sound can be heard.

##### Air Compressor

The Air Compressor compresses air to build brake pipe pressure. It's valve is found on top of the right cylinder.

##### Lubricator

The Lubricator oils the locomotive's valve gear. It's valve is found to the right of the S282's vehicle plaque.

##### Headlight Switch

The Headlight Switch controls the mode of the headlight & rear light. it has 7 positions (from top to bottom): high beam front, normal front, day running front, off, day running rear, normal rear, and high beam rear.

##### Gear Light Button

The Gear light button turns on a light below the right side of the cab, which allows the wheels & valve gear to be visible at night.

## Operating Manual

There is a in-game Quick Guide for the locomotive that player can buy at a shop.

Apart from that, the player has to buy a shovel and a lighter in any Shop.

## Trivia

***(92-)***

* The S282 appears similar to the American-made USATC S200 locomotive, an export design produced during WW2 for operations in the Middle East in 1941-42. This resemblance is likely unintentional.
* According to the nameplate on the locomotive, it was built in 1938.
* In reality, a comparable steam locomotive is always crewed by at least 2 individuals - a driver and a fireman. Ingame, however, the player must fill the role of both.
* From build 81, and until the bug was fixed in build 94, damage on the tender was disabled due to a bug that caused the tender to take excessive damage.
* The connecting rods on the driving wheels are incorrectly rotated 180 degrees apart from one another, when they should be rotated 90 degrees apart (as they would be in real life).
* Unlike the DE2 and DE6, the S282 has no warning light in the cab to indicate if the engine needs service so the only way to tell if it needs service is if it doesn't build up steam pressure despite the fire being lit and water being in the boiler.
* Likewise, the S282 does not have a warning light for incorrectly set brake pipes or brake valves.
