The Leetstell occupies a vast command centre within the Public Transport Administration of the Ministry of Mobility and Public Works, located in Kirchberg. Created in 2018, its purpose is to improve the comfort and all-round experience of public transport passengers.

As a true command centre open 7 days a week, it monitors all RGTR lines throughout Luxembourg (including cross-border services). Staff are tasked with diverting routes to avoid road blocks, adding additional services to meet user demand, optimising passenger connections and shortening or substituting a route for greater efficiency. In non-stop communication with the bus drivers on the ground via radio or the on-board computers, the Leetstell gives them instantaneous updates on traffic conditions. The service can communicate and display information directly on departure boards at bus stops as well as on in-bus screens, and also provides an audio version for bus drivers and passengers, keeping them on track before, during and after their journey.

The way the command post operates will be gradually fine-tuned and embedded as the RGTR network is re-organised in 2019-2022. Command posts for other networks (AVL, CFL, Luxtram, TICE) work alongside the Leetstell to gain an overall perspective and control of national and cross-border public transport flows.
