As you approach the bottom, the "Train" aspect kicks in. The long pole hits the bottom housing earlier. You feel a distinct "clack" of the pole hitting plastic, but instead of a painful thud, the Magmallow absorbs it. This is where the switch shines. When you bottom out a standard linear switch, your finger joints feel the shock. On the Nobara Train Magmallow Top, bottoming out feels like pressing your keycap into a soft felt pad .
You type all day for work and want a "pillow" at the end of every keypress, or you want a deep, non-meta sound profile for your next build video. nobara train magmallow top

Unlike traditional Nylon bottoms which produce a "thud," the Magmallow top (and bottom pairing) creates a porous acoustic signature. The plastic is not quite silicone, but it has a lower durometer (softer plastic) than standard ABS. This results in a bottom-out sound that is described as "marbly" or "squishy" in the best way possible—it eliminates the harsh clack. Typing Feel: The Train vs. The Marshmallow The name promises a contradiction: a heavy train and a soft marshmallow. How does that work in practice? The Press (The Train) Because this is a "Train" series switch, the stem poles are extended. This means the travel distance is shorter than a standard Cherry MX Red (4.0mm). The initial press is light—around 45g. However, due to the POM stem and polished rails, there is zero scratch . The smoothness is comparable to a well-broken-in Gateron Ink Black.

There is a slight suction sound on the return stroke due to the "Magmallow" material’s tight tolerances. It sounds expensive because, well, it feels expensive. Hotswap vs. Soldering The Nobara Train Magmallow Top features a standard MX-style pin layout (three pins or five pins depending on the batch). Most variants are 5-pin PCB mount , making them incredibly stable and eliminating wobble. This is where the switch shines
If you have spent any time on keyboard forums, Discord servers, or TikTok keyboard ASMR pages recently, you have likely seen this mouthful of a name floating around. Is it a train? Is it a marshmallow? Is it a character from Jujutsu Kaisen ? (Spoiler: No, but the name is a brilliant piece of marketing).
