Lisbon's iconic Tram 28 (28E) is officially scheduled to run every 8 to 12 minutes during peak hours, connecting Martim Moniz to Campo de Ourique. However, in practice, the service is notoriously irregular due to the nature of its route through the narrow, winding streets of the Alfama and Estrela districts. Trams are frequently delayed by double-parked cars, delivery trucks blocking the tracks, or high pedestrian traffic. Consequently, it is very common for two or three trams to arrive at once (a phenomenon known as "platooning"), followed by a frustrating 20-to-30-minute gap. In 2026, while digital boards at major stops provide real-time updates, they are often estimates. To avoid the longest wait times and the heaviest crowds, travelers are advised to ride either very early in the morning (before 9:00 AM) or late in the evening. If the 28 is too crowded, the 12E is a great "secret" alternative that covers many of the same scenic hilltop views with far fewer tourists.
