You need to find a copy of Benjamin Bernhart's "Reading Railroad Station Pictorial, Lines A-H" (there are 4 volumes in the series). It has pictures of Pine Forge, Colebrookdale, Boyertown, Betchtelsville and Barto stations. Pine Forge, Colebrookdale and Barto were the same design, it looked like a 2 story farm house.
According the the Reading Cabooses book by John W. Hall, in 1960 caboose class NMo 94017 was assigned to Pottstown for the Colebrookdale traveling switch engine. In addition cab NMg 92808 was assigned to pottstown as an extra cab and NMh 92820 was assigned to the Royersford TS.
Based on the caboose assignments there was one train that operated on the branch, a traveling switch engine.
In 1893 the branch had Psgr trains leaving Pottstown for Barto at 600a, 940a, 125p, 415p, 600p and psgr trains leaving Barto at 510a, 615a, 715a, 1105a, 240p.
in 1927 the branch had several 1st class trains 607, 633 NWD, 600, 602,632,610 SWD, 2nd class trains 601, 603, 605 NWD, 606 SWD and a 4th class pair of 648-649. All these trains operated daily ex Sun. The first class trains went out and the 2nd class trains came back in, that was a trick used by railroads to keep a turn schedule from delaying itself.
By 1941-1946 it was down to just two 2nd class trains, 605-632.
Keep in mind that the "two trains" was really one train that ran out and back (same with the 1927 trains).
