Model for 3D printing of a lever frame with interlocking box, as used in standardized mechanical interlocking (type Einheit) on German and Polish railways. Model contains parts for building a lever frame for 8 or 17 levers and up to 16 interlocking sliders.

Dwarf semaphore signal of standardised form utilized by German and Polish railways. Different build variants are included.

Signal gantry of the unified type designed for setting up to four mechanical signals, utilized by German railways, also present on Polish railways.

Model for 3D printing of a standardized points lever utilized in mechanical interlocking of type Einheit, commonly found on German and Polish railways. The model can be assembled as fully functional, including the emergency decoupling mechanism.

Signals and indicators of German Railways (Deutsche Reichsbahn-Gesellschaft, later Deutsche Reichsbahn) valid from 1935 till 1945, also utilized on occupied territories during World War II.

Standardized derailer utilized by Polish and German railways. The model contains parts for building the device in different variants: right or left derailer, derailer operated manually or via rod or wire transmission, single or coupled derailers. Model contains parts to assemble the derailer signal lantern.

Waiting signal utilized by German and Austrian railways also temporary in Poland during World War II. The model contains parts for building the signal in different variants.

Two-aspect mechanical distant signal with special construction to be mounted on signal gantries and signal bridges as used by German and Polish railways. The model allows for construction variant typical for Polish State Railways after 1959 (single signal shutter). The model contains additional parts to recreate the signal drive and manual on how to mount the signal on a light gantry.

Signal gantry of a lightweight construction for placement of a single mechanical signal (semaphore or distant signal), used by German Railways and found on some Polish rail lines. The model allows for placement of the access stairs from both sides of the gantry.

A standard mechanical distand signal utilized by Polish and German railways. Several construction variants possible: two or three-aspect signal (with two different contruction variants of the mirror chamber), signal on small or high post signal with mechanical or electric drive additional equipment: signal couplings, levers for coupling with main signal equipment for signals used by (…)
