By JOE SEXTON Movie makers descended yesterday on the Franklin Avenue Shuttle line in Brooklyn. They put fresh paint on the Franklin Avenue station and mounted new signs. There were scenes to be shot, and the crumbling, decrepit place had to appear to be a functioning subway terminus. The title of the work in progress: "The Money Train." "Great joke, huh?" said a conductor. Of course, there has never been much money for the Franklin Avenue Shuttle. For 117 years, it has conducted its creaking, lurching, relentless rumble through Brooklyn. Neglected and now macabrely ramshackle, the shuttle has stubbornly endured, carrying its daily loads of schoolchildren and working people to and from Bedford-Stuyvesant and Crown Heights. The announcement on Wednesday that transit officials were looking at further cuts in financing for the shuttle was just the latest blow. The line‹which connects the A train with the D, and thus Bedford-Stuyvesant to Coney Island‹ has not had serious repair work in decades, the most inspired civic intervention always coming when part of the line was near collapse. Inclusion of an $80 million rehabilitation plan for the shuttle on the Metropolitan Transportation Authority's list of capital projects is an annual rite. So is its being taken off the list. The shuttle was once more placed on the deferred project list several months ago, although a variety of scaled back versions of the plan, costing from $11 million to $33 million, are under consideration for 1996. The news this week that transit officials were considering closing the Dean Street station on the five-stop shuttle line, as well as considering ending all service late at night, was received by the ridership with sad smiles that looked a lot like practiced winces. To the people of the Franklin Avenue Shuttle, the real results of the proposed budget cuts‹the Transit Authority needs to close a $113 million budget gap‹just seemed like more punishment. "They have always threatened to kill the entire thing anyway, and I'm sure one day they will," said Pam Waring, a young woman who spent her childhood riding the shuttle and who yesterday was taking it to work. "It's easy to make fun of it or get dramatic about how awful shape it's in. But it's an essential part of our existence, and people use it." For many New Yorkers, the Franklin Avenue Shuttle is a kind of ghost train, with veteran city residents surprised to discover it has survived or that it even exists. But every day, it carries nearly 10,000 people along its 1.7-mile route to school or work. Its on-time rating of 99.6 percent is highest on the subway system. ("It's so good because it doesn't go anywhere," said Kenny Nesbitt, the superintendent for the line.) In the morning, the cars are packed with children going to Prospect Heights High School or nurses headed to Interfaith Hospital. The shuttle is a link to the Brooklyn Museum, the central branch of the Brooklyn Public Library and the Botanic Garden. Parents lug strollers and groceries and students carry bookbags into the decaying stations with a sort of melancholy faithfulness. On Wednesday night, people boarded at the Prospect Park station, unfazed by the construction signs on the platform that warned of asbestos and "cancer and lung disease hazards." Most of the stations look as if a tornado might have struck recently, and the scenery in between is mostly construction debris perhaps a quarter-century old. 'It does do something to the soul, the ego," Mr. Nesbitt said. The riders sat in a tired silence as the train, often pitching like a ship completed its latest uneven route down to Fulton Street. They got up and got on their way, grateful if not exuberant. "For the people who work, the conditions may stink, but the line is their life," said Manuel Goico, a store owner in Flatbush. Many shuttle riders seemed amused yesterday by the squawking from riders elsewhere in the city suddenly concerned about what budget cuts might mean for the quality of their service. "I'm happy, thrilled to see it," said James Lane, who said he had shuttled to and from Franklin Avenue for 43 years. "It's a taste of what we've been fed forever. And believe me, it's a taste that ain't easy to swallow." Back at the Franklin Avenue station, the movie technicians were busy placing lights and cameras. A specially designated train was going to be used for the shooting. A transit police officer said the movie, which stars Wesley Snipes, calls for a explosion scene on the train line. The officer wondered whether the city should allow it to be real, and thus save itself the demolition costs. Maybe that, he said, would get the renovation started at last. The regular riders stared at the bustle, asked questions and got on their trains. "You know, when I was in Guyana before I came to this country, I was warned about the Franklin Avenue Shuttle," said Joan Carmichael, who came to Brooklyn 18 years ago. "They told me it was dirty, dangerous. It is. But I'm here. Riding. Who knows how long it will last?"
