I like most model train persons born in the mid 1940's by the time 1980s arrived had a Penn Line K4. After getting a second one I wanted another one, but not a K4 but a earlier type to pull my set of MDC 60' wood style cars. I wanted a K2. Brass was out of the question. By this time my 3 kids had all arrived and I had to look to what I have my new K2 class locomotive. I had 2 Lionel pacifics. These Lionel had modified to allow their standard HO motor to within the boiler casting. They were lionel #0625 which had only a electric light? and when i got them very cheap. What Lionel added to the boiler appears as a small Belpaire firebox. The K2 had a smaller firebox than the K4. This became my K2. All photos I had seen up to that time showed a lower tender. I mated a Bachmann tender for a Reading 2-8-0 to my Lionel Pacific and Walla my new at the time PRR K2.
edit; What knowledgeable collectors will notice is this loco isn't a 0625, it has a smoke unit and pumping pistons to make the smoke puff out of the stack. I had gotten a 0635? drive and subustited drives. Now this loco is upgraded and? has a headlight and smoke unit.
