Thanks for this. So the controls seem to be what we're used to. I tried to get chatgpt to explain the difference between diesel electric and diesel hydraulic and it's hard for me to grasp how a diesel hydraulic works. Chatgpt said they are good for shorter lines and light trains. I wish I could understand more. Like, how does a dynamic brake work in a hydraulic system?
Diesel hydraulic is simple enough, the principle between de and dh are very similar. In de the diesel engine drives a generator making electricity. The electricity in turn drivers electric traction motors on the axles. In dh the diesel engine drives a pump moving fluid. The fluid in turn drives hydraulic motors on the axles. The dynamic brakes will likely be feathering the vanes in the pump and possibly also driving the motors backwards slightly.
Actually a real train driver just periodically releases the Sifa pedal to reset the timer cause in real life its a pedal thats constantly pressed but needs to be released every 20 or 30s. You can press the sifa in game and therefore release it periodically too. That way youll only get a Sifa light and acoustic warning if you forget to release it. The tutorial apparently states that you should start with 2nd gear and only switch to higher ones after the gear light turns off. Same with getting back to gear 0: Go back to 2, wait for the light to go out and then to 0.
Got word from a rea life driver - this depends on the age of the loco. Older machines are like they are in game. Newer machines work the way you describe. I have one game where you hold down a deadman (spacebar) all the time and lets just say I never play it :).
@@trainsimulatordriver Oh okay, thanks for the information. But just to make sure: They just press a foot pedal. Its naturally pressed down when you rest your foot so it doesnt get uncomfortable. Some locos still have extra Sifa buttons in addition to that foot pedal though. The game just simulates the Sifa pedal being constantly pressed and you pressing the Sifa button actually releases the pedal. You can test this if you just stand up from the driver seat with active Sifa. Then the Sifa pedal wont be pressed anymore triggering the system and applying the brakes
@@Guy-Zero yeah it works it backwards for those with pedals - imagine pressing Q continuously - your finger would get very sad. We had trams with a middle throw pedal - you had to hold it in the middle, lift it up and you stop, push it down and you stop - they were a pain
Is the dynamic brake electric or hydraulic? I keep watching the gearbox oil temperature gauge because it seems to creep close to the red line when driving, and I recall someone telling me a while ago that hydro-dynamic brakes can be a bit of a fire hazard on trains because of the extra momentum in comparison to road vehicles.
Brilliant video Paul as usual. Thank you.
You're welcome I hope it's useful
Great Video, Well presented.
Thanks heaps 😁
Funny you mention the ears as the 218s are nicknamed bunnies
@@keironriley that's cool 😀

Oh as an aside never ask generative ai like chatgpt unless you already know the answer because if it doesn't know it'll make it up.
You Look cold mate. are you in NZ ha.. Always enjoy your vids and banta.
Hehe no Melbourne. NZ's western suburbs

@@Guy-Zero pressing a button constantly is going to be very uncomfortable let me check with a German driver I know

It has to be hydraulic. There's no electric traction motors.
@@trainsimulatordriver I assumed it was hydraulic but some early Allison bus transmissions apparently had electromagnetic retarders fitted.
Checked some real life videos. It actually looks like the v-shaped stacks ARE the exhaust pipes. I found an engine startup here on RUclips.
Cool, it does seem like the smoke comes from them most of the time
