| Types of the ballastless tracks | Components | Loading at the slab center | Loading at the slab end | Longitudinal stress (MPa) | Transverse stress (MPa) | Longitudinal stress (MPa) | Transverse stress (MPa) |
| Standard assembly | Top of track slab | −0.65 | −0.55 | 0.33 | 0.26 | Bottom of track slab | −0.98 | −0.87 | −0.65 | −0.64 | Top of base plate | −0.65 | −0.49 | −0.92 | −0.81 | Bottom of base plate | −0.40 | −0.46 | −0.56 | −0.42 |
| Subballasted mat | Top of track slab | 1.60 | 1.72 | 0.98 | 0.90 | Bottom of track slab | −1.30 | −1.18 | −1.63 | −1.67 | Top of base plate | −0.52 | −0.62 | −0.74 | −0.92 | Bottom of base plate | −0.33 | −0.34 | −0.52 | −0.54 |
