They've made alot of progress on trail improvements- most of it has been graded and rolled and they started putting crushed limestone down this winter. most of the bridges are complete- I believe you still need to watch out for one spot north of New Bethlehem where there is no bridge at all going across a roadway.
I look forward to doing some winter hiking and seeing the icicles hanging off all the rock cliffs along this trail.

some good places to view the icicles anytime it is cold enough:
Moore Road near Brookville---
Heathville on the downstream side---
and about 1 mile downstream from New Bethlehem

This is a very scenic trail and easy to get to many different parts to do one section at a time.

I was pleased to find that the Redbank Trail group is making wonderful progress on what should prove to be one of the most spectacular trails in the region! Of course, locating railroad artifacts on these trails is my game, and what a bonanza we have up here along the Redbank Creek. My first rendezvous with the trail was at the currently convenient midpoint parking spot, the old Summerville Station. This is where the old Lake Erie, Franklin, & Clarion Railroad interchanged with the Pennsylvania's Low Grade Secondary Track (the Redbank Trail). The LEF&C has vanished without a trace (abandoned 1993), while trail committee member Jim Hummels, who I encountered riding the trail, tells me the coal-hauling Low Grade line was abandoned about 8 years ago. Right at the post office parking lot, note ex-PRR cast iron milepost 34 / 76 (along with a modern ex-Conrail metal milesign 34). This is a classic "dual numbered" (and rather rare) gem, indicating 34 miles west to the line's junction with the north-south Allegheny Valley Line at East Brady Junction, and today's north-south AV Trail, this trail's eventual western terminus, and 76 miles east to the line's former junction with the north-south Harrisburg-Buffalo main line at Driftwood, PA. Heading south, Milepost 33 is a CUT STONE relic, similar to those I found on the Allegheny Valley Trail, this one also accompanied by a metal Conrail mile marker. Painting mileposts became a maintenance headache, so they just started plopping in those cheap reflective signs in the mid-1980's. Cut stone Milepost 32 is sliding down over the river bank, almost buried by the old ballast. Next we see another one of those classic cast-iron dual mileage posts, "31 / 79." Note how the appropriate number faces the train travel direction. This one is very rusted. I do hope the guys up there retain and repaint these classic beauties! Something got the old milepost at MP 30, as only a metal sign remains here. And my southernmost point on this trip was cut stone Milepost 29, and its Conrail counterpart milesign. This trail is not finished and, although scraped, I found myself riding on mostly half-inch to one-inch ballast stones, a little tough to navigate over at speed. The bridges on the five miles south of Summerville are finished now, with beautiful, smooth, new wood decking and guard rails. There is a short, feeder stream bridge 2.6 miles south of Summerville, and a big, beautiful, curved plate girder trestle 3.2 miles south of town. Jim told me that all of the bridges are finished now, save for a few at the west end of the trail, west of New Bethlehem, and that the trail is rideable, in this current condition, to Brookville. The tunnels out at the west end are going to be a problem, and they are currently closed. The scenery along Redbank Creek is just as a previous reviewer stated, similar to that of the Grand Canyon of Pennsylvania. Huge hemlocks and mountain laurel line the very isolated trail, quiet and peaceful. No road noise anywhere, even though you are only a short distance east of paralelling PA-28 (the "rollercoaster"). If my first five miles along this trail is any indicator, (and Jim says eastward is even BETTER!) this trail is going to be one of the certain "must-do" trails in this region. You WON'T be displeased with what you see along the Redbank Creek. When we get that finished surface, this will be a 5-star trail!

Some further details on Patton Road access:
It's about three miles on Dairy Road, three tenths mile on Cunningham Road, and one mile down Patton Road. This is a narrow, single lane dirt road, so if you meet a vehicle coming from the other end, one vehicle will have to back up to the rare pull over. There was no road sign for Patton Road in October, 2010. For these reasons I would recommend using other access means discussed below.

You can find limited, unofficial parking where the trail crosses paved hiways at Mayport, Heathville, Summerville (near Post Office) & Baxter, PA. We rode bikes from the Mayport bridge (about a half mile off Rt. 28), past the Patton Rd parking, to a bridge near Heathville. Very scenic, reminded us of the PA Grand Canyon!
This area was graded and rolled, fine for mountain biking even without the finished surface.

For a quick check on trail progress:
Along Rt 28, about halfway between Summerville and Baxter, you will find Morre Road near a hill crest (watch closely!). It's just a short distance to where the trail crosses this road, and you can park here to view two examples of bridges within a quarter of a mile on either side of Moore Road. The nearest one has railings and metal grid walkways. This area was more suitable for hiking, still rough gravel & ballast.

There appears to be about ten miles rolled now. This will be a great Rails to Trails when completed, but even in its' present state was quite enjoyable.
