Introduction

This blog is for the various different feats in Castlevania that I'll be calculating, as I now just put all my calculations for one verse into one blog to make them far easier to find.

Jonathan and Charlotte Stop a Full Moving Train

Jonathan and Charlotte together stop a train moving at top speed, for reference, they have the strength glove relic to even be able to do this.

To calculate the force required to stop a 1944-era steam train, we need to use the formula for force:

Force = Mass × Acceleration

We assume the following values:

• Speed: The top speed of a 1944-era steam train is approximately 100 km/h (converted to 27.8 m/s).
• Mass: We'll use the value of heavy locomotives such as the Union Pacific Big Boy, which weighs 540 long tons, which is approximately 548,665 kg.
• Time: The train gets caught at 3:17 and fully stops at 3:23, so 6 seconds.

The acceleration (or deceleration) can be calculated using the formula:

Acceleration = (Final Velocity - Initial Velocity) / Time

Since the final velocity is 0 m/s (the train stops) and the initial velocity is 27.8 m/s:

Acceleration = (0 - 27.8 m/s) / 6 s = -4.633~ m/s²

Now, using the mass of the train:

Force = 548,665 kg × -4.633~ m/s² = -2,541,964.945 N (Newtons)

Thus, the force required to stop the train in 6 seconds is approximately -2,541,964.945 N.

For note the negative sign just indicates that the force is applied in the opposite direction of the train's motion, which is expected during deceleration (slowing down or stopping). It still is the same magnitude required whether negative or positive, so the feat itself would still be them stopping 2,541,964.945 Newtons.

For reference, this is Class K.

Oh yeah, since Jonathan and Charlotte did it together, we'll divide it by 2.

2,541,964.945 N/2 = 1,270,982.4725 N, still Class K.

Who does this scale to?
This one is pretty hard since not only are Jonathan and Charlotte using a direct amplification to their lifting strength in order to do this, but they're doing it combined. Along with this, Jonathan and Charlotte are no slouches, being the second strongest non-vampire protags (not counting Soma Cruz) as they come right before Julius Belmont so I think for now I'll just have it only apply to Jonathan and Charlotte. As it's not only combined but through gear that amplifies their lifting strength.
