The 4-4-4 'Bumblebee' Class Mining Steam Locomotive

*******************************************************************************************************************
Firstly I wanted to thank creators of all those amazing mods we are using: Equinox, peaceman, wolfgar7474, C3ntron and STORI3D PAST Productions

*******************************************************************************************************************
Technical data:

- max width: 7 blocks (1.75 m)
- max height: 9.5 blocks (2.37 m)
- max lenght: -- blocks (-- m)
- number of engines: 2x small (50HP)
- driving wheel size: 3 (small)
- number of driving wheels: 4
- number of weighting jars: 2
- suspension: X-RAI spring suspension mk I, miniaturized version.
- max speed with no load: > 80 km/h (50 mph) [It will be tested to full extend shortly]
- max load while maintaining 15-40 km/h: 40 t @ 4° *
- max absolute load: 50 t @ 2° * [The suspension will be updated shortly and then it probably will pull more]
- max weighting needed: 4 t @ 50 t load

*Grades bigger than 5 have not been tested, as I consider them unrealistic. The engine should work just fine with steeper slopes, but the maximum possible cargo load may decrease a bit.

Description:

Xaerthus's Rail & Air Industries are always in search for solutions in yet unknown territory. That is why we bring you the first ever locomotive, build specifically for the narrow gauge mining rails! No more pulling carts with ropes. Now you can use a proper engine for that. It has everything a big locomotove has to offer, just in smaller scale. Due to its small size and height it should fit in even the most cramped tunnels and has no problem going through one large block gaps.

*******************************************************************************************************************
Setup instructions:

Just place on a straight piece of track and it's ready to go! It is neccesary to wait a bit for the engines to get to temperature (that small bar that rises in the recess above the fire pit) before moving. It may have slight difficulties otherwise.

*******************************************************************************************************************
Operating hints:

- The engines can be reached for switching/grabbing throttle from the ground.
- The engines can be refueled by clicking on the down-rear part of the side of the engine from under the sideskirts. It is a bit tricky at the beginning but once you know where to click, its easy to use.
- If the wheels slip and the engine wont move, it needs more weighting. Place heavy items (ingots, weights, dirt) into the 2 weighting jars (located between the driving axles).
- Clanging and crackling noises are normal and should not be worried about.
- The engine has no breaks. To slow down, just decrease the throttle. If more stopping power is needed, throttling up in reverse works great.
- When pulling heavier loads it is good to have a bit longer connections to be able to start the cars by 'jerking' them. Otherwise you might be unable to move.
- It is wise to occasionally check the wheels for damage with a hammer. It has never happened during testing, but better safe than sorry.
