While there weren't many motor cars and lorries around at the time (some steam cars and wagons though), there must have been other traffic. Even if everyone didn't have their own horsedrawn vehicles at home, there would have been deliveries, etc. According to the old map, the buildings north of Rugby Road don't look residential but are unlabelled, so there could have been a works/depot entrance which needed to be kept clear for a queue of incoming vehicles, or rather the queue that would form regardless would block tram services otherwise.It seems a bit odd to have the tracks interlaced in 1901, particularly as there are houses on the south side. The building on the north side may be a business, but would the tracks been interlaced to avoid inconveniencing one business?
