springs_2springs








If using compression springs for suspension on locos, bogies, etc we recommend you decide what weight you need that item to be able to carry (or its resting weight in the case of locos) then double it for the lb at full compression. If you then put a spring (or multiple if need be) on each axlebox to meet that maximum compression then when on the track the axleboxes will sit halfway up in their slots/ on the spring meaning they have movement both up and down to follow the track.
If using them on rolling stock where the weight is an unknown and varies massively we recommend putting a longer lighter spring as well as a shorter heavier spring on each axle box, this allows the axle to move and up down under low or no load on the lighter spring but also allows it to take the weight of a fully loaded coach onto the heavier spring.
