Yup! Which is why some steam trains had starter gear or “boosters” which was a 3rd piston geared down a lot into a normally unpowered axle. It was only active at low speeds but provided extra starting torque to get things moving

In order of most frictiony to least frictiony

Stiction (stationary object you forced to move)

Rolling

Sliding

Which is why ABS exists. When you lock your wheels up your coefficient of friction tanks and your stopping distance can double or more depending on conditions. ABS unlocks your wheels sometimes so you can at least steer, unlike a skid. If you know how to pump brakes properly a skilled driver can beat ABS handily.

There’s also the fact that couplers have these hard rubber disks that act as springs and shock absorbers (railroading is kind of caveman-like in its solution to things) so when you try to pull a train it might look like you’re moving but you’re just taking the slack out. If you don’t you can bust a coupler from shock loading, so you can’t cheat physics that way (how I move heavy furniture around by myself personally so you would think it applies to trains)

As a result you take the slack out of a train and make the cylinder part of the boiler until:

A) she moves!

B) your wheels slip!

Once it’s moving it’s easy going.

As for why an electric engine can’t keep hauling overloaded it’s because it’s above 100% rating. It can only do that for a short while or things start melting and letting out magic smoke.

A steam locomotive can haul anything it can get moving since it’s lower friction once rolling, and requires less drawbar force.

It’s a common railroader saying I replied to the other commenter with more details if you’re curious

It’s a railroader saying. Steam makes 100% torque at a dead stop so if it can start moving it can haul it.

So it means if our little train gets going nothing can stop it.

For comparison a diesel-electric locomotive makes 300% torque at a dead stop so it can move things it cannot haul for long distances. The motors would catch on fire or you would burn out your electronics.

Another railroader saying that sounds like a tautology is

“Steam can’t start a load it can haul. Electric can start a load it can’t”

“any load a steam locomotive can start from a dead stop, it can haul”

You’ve got this, little meme locomotive!

Same here. It’s daily updates that work perfectly and constantly improve UI/UX. Revanced is like a broken down Ford now who knows if it’ll start or work.
