Lubricating, an important issue
The majority of the TS2015 and 3rd party engines does not support the lubrication process. Some 3rd party engines does have a lubrication process and within their scenario’s it is even required to use the lubricator prior to departure. The lubrication by hand, using an oil can, hand pump or grease injector for every rod, axle, bars, pins, etc, are not simulated, only the lubricator itself is operational.
Third party developer and software producer Just Trains provides the lubrication process with the Advanced 4MT, 5MT, 6MT and 7MT. In order to use the lubricator make sure the engines handbrakes are set.
If you own a 4MT, 5MT, 6MT and/or 7MT from Just Trains/steamdevs, the lubricator is operational prior to the run when the hand brakes are set by pressing [ / ]. Then press [ Y ] for about 5 seconds.
The importance of lubrication
Oil is used to lubricate all motional parts at the engine. Motion is substitute to friction. Friction causes heat and when steel becomes too hot, the steel will encounter severe damage. Axles and pistons needs to be lubricated by every time occasion. The driver checks always the temperature of the pistons, rods and bars due to frictional movements.
During the run, a rod is installed between the piston of the last axle and the lubricator. The rod operated the mechanical oil pump at every rotation of the last driving wheel. The mechanical pump then distributed the oil using a small brass pipe to the “unreachable” motional parts independently from each other.
The amount of oil for each motional part can be regulated separately depending the need and quantity of oil at every swing the rod is operating the lubricator. When the engine is stationary, the lubricator once and a while needs to be operated manually. Though after a period of time and prior for the next run, the lubricator spindle needs to be rotated manually as well to ensure the lube reaches of all the connecting points and surfaces of the motional parts.
Depending the type of engine, railroad company and country you will start to lubricate when the boiler pressure starts to rise. All motional parts has to be lubricated. Once started to firing up, the oil cans needs to be filled up with the proper oil or grease. You just cannot use all sorts of mineral oil. The grease or oil must fulfil industrial lubrication requirements. Mostly this is special oil with an cohesive number.
The lubrication of all motional parts, pistons, rods and bars is not simulated in most cases. Some advanced engines like the 4MT and 6MT from Just Trains has the lubricator working.
The German lubricating system
To lubricate an engine different type of oils ar used. The oil cans at German engines are assigned with colored lids for recognition.
Cylinder Oil (blank lid with a red A)
Oil (cohesive value: 1000) used for cylinders only, it can handle temperatures up to 400 degrees C.
Thick Oil (red lid)
Oil (cohesive value: 1000) used for water and air pump and can handle temperatures up to 400 degrees C.
Thin Oil (yellow lid)
Oil (cohesive value: 220) used at pistons, axles, rods, motional bars, levers, lubricators.
This oil is not suited for high temperatures, but can stand up to 130 degrees C.
4. Used oil.
A mixture of all oils to lubricate couplers, simple motional bars, truck pins, springs and door pins, coupler bars between tender and engine. This oil is not suited for the named equipment in the mentioned lines 1, 2 and 3 above.
5. Polishing oil.
A mixture of petrol, thin oil and think oil. This oil is slightly warm when used. This oil is to polish the plate work of the boiler and engine. This will also preserve the plate work of the engine and prevents corroding and creates a thin layer of oil on top of the plating reflecting a half matt glossy shine effect by the sun glare or light poles.
Used to lubricate buffers, coupler pins and bars, screw bars, truck studs, boiler sliders and locker nuts.
