PartyBus – AEC Routemaster RML

Double-deck advertising bus operated by PartyBus seen on Rua Cintura do Porto, Lisboa, in June 2026. This double-deck bus adapted for mobile events and advertising purposes is an AEC Routemaster RML first registered in 1967. It is presumably the former RML 2723 (SMK 723F) of the London Transport. It has a Park Royal Vehicles body and an overall length of 30 ft, and could originally accommodate 72 seated passengers (H40/32R). Based in Lisboa, PartyBus provides various means for mobile events and advertising. Here, we see this iconic AEC Routemaster RML next to the Tejo River in Braço de Prata, as part of the "3rd Classic Car Rally", with the Lisboa–Poceirão–Azeitão route, promoted by Clube Ás. As an interesting note, the RML ("Route Master Long/Lengthened") was the high-capacity version of the Routemaster, easily recognizable by the square windows in the middle of the body. It served on major London routes. ●

Autocarro publicitário de dois pisos operado pela PartyBus visto na Rua Cintura do Porto, Lisboa, em Junho de 2026. Este autocarro de dois pisos adaptado para eventos móveis e funções publicitárias é um AEC Routemaster RML com primeiro registo em 1967. É presumivelmente o ex- RML 2723 (SMK 723F) da London Transport. Tem uma carroçaria Park Royal Vehicles e um comprimento total de 9,14 m e originalmente podia acomodar 72 passageiros sentados (H40/32R). Baseada em Lisboa, a PartyBus disponibiliza diversos meios para eventos e publicidade móvel. Aqui, vemos este icónico AEC Routemaster RML junto ao Rio Tejo, em Braço de Prata, integrado no "3.º Passeio dos Clássicos", com o percurso Lisboa–Poceirão–Azeitão, promovido pelo Clube Ás. Como nota de interesse, o RML ("Route Master Long/Lengthened") era a versão de grande capacidade do Routemaster, facilmente reconhecida pelas janelas quadradas a meio da carroçaria. Prestou serviço nas principais rotas londrinas. ●

The AEC Routemaster RML during a visit to Casa Ermelinda Freitas, in Águas de Moura, Palmela. Even with its roof removed and adapted for mobile events and advertising functions, this bus still preserves several details associated with its time in regular passenger service in London, including maps of the "London Overground" network. ●

Ainda que com o tejadilho removido e adaptado para eventos móveis e funções publicitárias, este autocarro preserva ainda vários detalhes associados ao seu tempo no serviço regular de passageiros em Londres, incluindo os mapas da rede "London Overground". ●

A road through the rural landscape of southern Portugal, with the blue sky as a roof. The Routemaster stretching its legs, its voice echoing across the fields. Memorable. ●

Uma estrada pela paisagem rural no sul de Portugal e o céu azul como tejadilho. O Routemaster a esticar as pernas, a sua voz a ecoar pelos campos. Inesquecível. ● 

And above us, nothing but the endless blue sky. ● 

E acima de nós, nada mais que o infinito céu azul. ● 

Personal Memories

As for the rear-entry buses, the Lisbon equivalent of the Routemaster—the elegant AEC Regent Mark III with Weymann bodywork. On it, I had a whole personal geography. On the lower deck, I would sit in the front seats to listen attentively to the engine and the peculiar transmission, or in the back seats, right above the wheels, next to the door, to be thrown into the air by every imperfection of the cobblestone streets. On the upper deck, I would sit in the back seat next to the stairs to flirt, or else, in the front, I would travel standing with my head out the window, feeling the wind on my face or, sometimes, a tree branch left untrimmed. ● 

Quanto a autocarros com entrada traseira, o equivalente lisboeta do Routemaster—o elegante AEC Regent Mark III com carroçaria Weymann. Nele, eu tinha toda uma geografia pessoal. No piso inferior, sentava-me nos bancos da frente para ouvir atentamente o motor e a peculiar transmissão, ou nos bancos de trás, mesmo por cima das rodas, perto da porta, para ser atirado ao ar por cada imperfeição das ruas empedradas. No andar de cima, sentava-me no banco de trás perto das escadas para namoriscar, ou então, à frente, viajava de pé com a cabeça de fora da janela, sentindo o vento na cara ou, por vezes, um ramo de árvore deixado por aparar. ●
