LI train masters on board for biggest show yet with infamous Sopranos setpiece: The original bloodstains are still there

They trained over a year for this.A Long Island model train club is all aboard for its largest-sized open house, having spent 16 months crafting a 6,500-square-foot display — placed alongside an iconic, blood-splattered set piece from “The Sopranos.”“It’s gotten bigger and better than ever … I’m putting in 30 hours a week here,” Steve Scagnelli, president of the Train Masters of Babylon, told The Post.The 70-member strong TMB transformed a vast basement in the Upper Room Church of Dix Hills into a hobbyist’s paradise where new and old model trains buzz by towering skyscrapers from New York City, oil refineries of the New Jersey Turnpike, the Horseshoe Curve of Pennsylvania and several other landmarks.The tireless passion project, which runs around $100,000, will be on display at no charge for an estimated 700 newcomers this Saturday and Sunday afternoon before shifting back into “work mode” for another year of set design.“We’ve got two main lines running up to three trains, two more branch lines on top of that, and beneath the display, we have a special subway system running up to four at a time,” Scagnelli, a founding member from 1994, said.“There’s lots of clever things there, too.One bridge is made out of a former member’s picnic table, a water tower on display made out of a tuna can, and one train with some Lego figures on it.”The TMB faced one of its biggest challenges before the project even got going: moving to a facility nearly double the size of its old Farmingdale outpost once their lease ran out.After clearing out the new digs — filling up nine dumpsters of garbage in the church’s basement as an all-hands-on-deck project — the group began construction on the most extensive display it has ever made.“It took a month alone just to create the layout and electrical engineering before we could even begin with the trains,” added Scagnelli.

“People have worked on this four days a week since we started.”However, n...
