An unlocking system for at least one brake of a bogie includes an unlocking device configured for being attached to at least one cable connected to the at least one brake, and a support that includes a shaft forming a first axis of rotation. The unlocking device is rotatable with respect to the support about the first axis of rotation between a rest position and at least one unlocking position. The unlocking device is configured for exerting a traction on the at least one cable. The unlocking system can be produced at least partially by additive manufacturing.

A railroad brake stick head has a head body formed of a lightweight durable material. A railroad brake stick head includes a head body having two opposing planar surfaces spaced apart by at least one sidewall that includes at least one concave sidewall region, wherein the head body is formed of a first material having a first hardness. At least one brace implant is at least partially embedded in at least one concave sidewall region, wherein each brace implant is formed of a second material having a second hardness that is harder than the first hardness. The head body includes at least one implant recess formed into the at least one concave sidewall region, and the at least one brace implant is in the at least one implant recess. Each brace implant can be coupled with the head body, such as by friction fit, adhesive, fastener, or combination thereof.

Disclosed is trolley brake and an assembly including a trolley brake. In some embodiments, the assembly may include a channel member, and a trolley body having a first portion positioned within an interior of the channel member and a second portion extending from the channel member. The assembly may further include a locking device coupled to the trolley body, the locking device including a main body coupled to the second portion of the trolley body, a bar extending through the main body, wherein the bar is rotatable about a central axis, and a stopper coupled to a first end of the bar, wherein the stopper comprises a magnetic material. In a first position of the bar and the stopper, the stopper is in direct physical contact with the channel member, and in a second position of the bar and the stopper, a gap is present between the stopper and the channel member.

A durable tool includes a head with a hilt region featuring a head interlocking groove extending from a hilt end through at least a portion of the hilt region. The tool further includes a cross-support having a support region with a support interlocking groove extending from an interlocking region end through at least a portion of the support region. The support interlocking groove is configured to interlock with the head interlocking groove such that the hilt region is received into the support interlocking groove and the cross-support is received into the head interlocking groove, thereby forming an interlocking region. A handle is fixedly coupled to the head and cross-support, with the interlocking region positioned within an end of the handle. This configuration provides enhanced structural integrity and durability for the tool.
