Some tram systems advertise their depot workings and enable one to ascertain the regular use by passenger-carrying services of junctions or sections of line that do not otherwise see public service. This occasional series lists such services that have come to notice. While the data for each system is current at the date stated, it is not the intention to endeavour to keep every entry up to date at every service change - the listing serves as a guide for travellers as to the sort of services they can look out for, enabling them to check current published timetable material at their time of travel.
To assist in tracing services, the route and/or timetable number for each journey is shown in parentheses, e.g. (1). Days of operation are in English notation (respectively: Su, M, T, W, Th, F, S) - plus "O" for only, "X" for excepted. Su (Sundays) usually includes public holidays in mainland Europe - but check locally.
Listings for other systems throughout the world - in the same format as shown below (please include date of timetable validity) - will always be welcomed.
