VR Finland steam locomotive load tables (1936)

Load tables and performance curves for Finnish locomotives may not be too common outside Finland. This time our booklet is Kiertokirje N:o 10/2187, syyskuun 21 päivänä 1936 (September 21, 1936). It has 30 pages of text, 125x175mm, no illustrations. It gives load tables to steam locomotives at different gradients and list max gradients on every railway line and on main industrial or harbour branches. Our samples show load tables for 10‰ (1 in 100) and 12.5‰ (1 in 87).

Naturally the 1885 classification is used as the new one was introduced only in October 1942. Conversion from the old to the new classes is given below:
D1 = Vr2
G1, 2, 4 = Sk1
G1, 6, 9 = Sk2 (note G1, some became Sk1, some Sk2 and many were already withdrawn by 1942)
G3, 5, 10, 11 = Sk3
G7 = Sk4
G8 = Sk6
G12 = Sk5
H1, 2 = Hk1
H3 = Hk2
H5 = Hk3 (all H4 and three of H3 were rebuilt as H5)
H6 = Hk5
H7 = Hv4
H8 = Hv1
H9 = Hv2, Hv3 (Hv2 3-axle tender and Hv3 4-axle tender)
I1 = Vk1
I3 = Vk3
K1 = Tk1
K2 = Tk2
K3 = Tv1
K4 = Tv2
K5 = Tk3
L1 = Vr1
N1 = Pr1
O1 = Vr3

Columns 1-3 in the tables represent:
1 = always (winter and summer)
2 = no snow on rails, temperature higher than 0C
3 = on discretion of the driver
