Our train is stopped at Science Park 
      station in this scene, and an inbound train approaches on the opposite track.  
      Once we have finished our passenger business, forward movement will be 
		limited to 6 miles per hour, temporarily, on this portion of the viaduct.  
		 
		The Science Park station was a later addition (mid-1950s) along the 
		Lechmere Viaduct.  Streetcars originally went from North Station out to the last stop with no intermediate stop. |
