The two sets that you mention are the oldest set models of subway / el cars that either company ever did however MTH did do the BRT / BMT Standards that operated from 1915 thru 1969. Each car is 67 feet in length. They came as a 3 car set with one powered car and two non-powered cars and a 3 car set of 3 non-powered cars. I own 2 of the powered car sets. MTH came out with them in 2006. I am quite sure that they never did a second run of them as they did with most of the other subway car sets. The catalog number for the powered set is 20-2675-1. The catalog price was $450.00. 3 of the remaining cars are part of the TA operating fleet and are at the TA's Coney Island Shops. A 4th car is in the TA Museum in Brooklyn. A 5th car is at the Sound Shore Line Trolley Museum located in East Haven, CT. The Standards also ran on the Myrtle Av. Line that was rebuilt around 1918 north of Broadway in Brooklyn to handle the heavier subway cars. This is where the cars also ran last in 1969. I use to see them stored in that yard in late 1969 along with the Q cars.
