Definition of "honourably"

Inevitably the present extent and variety of the Belgian railways will diminish, and within the space of the ten-year plan we can expect to see a modern system concentrated on the main traffic routes like its neighbour in the Netherlands, and with its last steam locomotives and wooden coaches honourably retired to the museum.
