F7A 1716, F7B 3873, F7A 1648 the only F7A painted blue, F7A 1744 are just leaving out of Collinwood yard heading west. We see the crew has propped the nose door open to catch a breeze on this hot day. As this train was leaving we didn't have motor drives for our cameras so we would shoot and run ahead to shoot again. The crew must have got a laugh out of this for one of them yelled out if we had $20.00 dollars they would stop the train and let us take all the photos we wanted. We didn't take them up on the offer.
