Lütze Transportation GmbH

What Lütze Transportation GmbH does

Lütze Transportation GmbH is a German private limited company (GmbH) that designs and manufactures electronic and electrotechnical components specifically for rail vehicles. Founded in 2012 as a reorganization of the transportation division of the LÜTZE Group (originally established in 1958), the company is headquartered at Bruckwiesenstrasse 17-19 in Weinstadt, Germany, and operates with a small team of approximately 15 employees.

The product portfolio is organized into three categories: Control Technology (Vehicle Control Unit, distributed I/O, LEOS Ethernet switches, and TLM Train Line Modem, anchored by the LION system platform), Interface products (relays, transducers, power supplies, and USB-C charging solutions), and Indication (LED indicators, lighting, and buzzer components). All products comply with EN50155 railway standards, and the company has maintained ISO 22163 (IRIS) certification since 2007, placing it among the earliest certified rail-electronics suppliers globally. Coverage is also mapped to adjacent standards (EN50126, EN50128, EN50129) relevant to safety-critical rail electronics.

Lütze Transportation sells B2B to rail vehicle manufacturers (OEMs) and operators via direct enterprise sales channels. Named customers include SBB (Swiss Federal Railways) and HARSCO Rail Europe, with the HARSCO partnership dating to 2000. Revenue is generated through hardware sales of both standard catalog items and custom-engineered modules tailored to specific vehicle platforms. Following its October 1, 2024 acquisition by Amphenol Corporation (NYSE: APH), the company operates as a wholly-owned subsidiary while preserving its brand, locations, and customer relationships.

Core offering

Lütze Transportation develops and manufactures electronic and electrotechnical components for rail vehicle applications across three product lines: Control Technology (vehicle control units, I/O systems, Ethernet networking), Interface (signal conditioning, power supplies, relays), and Indication (LED signaling, lighting, dimmers, buzzers). The company also delivers custom module development and platform solutions, supported by configuration and programming software tools. All products are designed to comply with EN50155 railway standards and ISO 22163 (IRIS) quality certification.

Product overview

Lütze Transportation GmbH offers a comprehensive portfolio of electronic and electrotechnical components specifically designed for rail vehicle applications, organized into three main product categories: Control Technology (Leittechnik), Interface, and Indication (Signalisierung). The Control Technology category centers on the LION system platform, a complete control system compliant with EN50155, EN50126, EN50128 and EN50129 standards, comprising the vehicle control unit (CCU 800103) and distributed I/O modules, complemented by the LEOS Ethernet switch and TLM Train Line Modem for network connectivity. The Interface category provides products for signal conditioning between control systems and actuating elements, including diode and resistor modules, relay modules, transducers, temperature controllers, power supplies, and the 60W USB-C Power Delivery charging system. The Indication category offers LED indicator lights, LED lighting elements, LSG3 control units for external vehicle lighting, dimmer modules, and buzzer components for visual and acoustic signaling. All products comply with EN50155 railway standard and are supported by software tools including MULTIPROG (IEC 61131 programming), SAFEPROG (safety programming), and the LÜTZE Config Tool for device parametrization.
