Track Crew Work Party
Once again, the Track Crew went back to work changing ties in the operating track.  The work this day started on the Tail Track between South Park and Diablo Vista.  This meant that train operations during the tie replacement work would be significantly curtailed, since there would be no access to the Sacramento Northern main track.  Due to the expected number of visitors for the day, the Crew had agreed to work on the tie replacement only during the morning, and release the track for normal operations in the afternoon.  So the Crew went to work, knowing they had only a short time to complete the work.

The new feature of the day was use of the steel battering ram constructed earlier.  This short section of I beam was gripped in the jaws of the Tie Inserter.  After the spikes had been pulled, the battering ram was used to start the ties out from under the track by pushing on the end.  Then the battering ram was released, the machine was turned around, and the ties gripped in the normal way to pull them the rest of the way out from under the track.  This turned out to be a good way of getting the ties out, with only a few suffering from the end of the tie breaking off while being pulled out.  These few required extra hand work to get the old ties out, but all of the others were extracted and inserted without special effort.  This was a major victory, since the overall job has much higher productivity with much less physical effort when the machine works as intended.

After the track was buttoned up and turned back over to normal train operations, the Track Crew reconvened at the South Shop Switch to replace a few more ties safely out of the way of the trains.  These ties were complicated to change due to the close clearances between the adjacent tracks and the Car House Two building. 

The most difficult were two ties holding the switch stand.  Fortunately, these two were so thoroughly deteriorated that they easily broke apart for removal.  The replacement ties required significant excavation a bit of jacking of the track in order to coax them into place.

Battering Ram

A "Battering Ram" for Tie Replacement
Some success has been had using a small section of a tie like a battering ram, to grip in the jaws of the Tie Inserter and begin pushing out the old tie to be changed.   Then the machine can be turned around, and the old tie gripped in the jaws to pull it out the usual way.  This helps to reduce the problems with the end of the old tie splintering, which often results in the machine loosing the grip on the tie, and then it is stuck under the rail.  By pushing on the old ties first to get them started, the machine is able to get a better grip, and do its job more effectively.  Using a section of a tie as a battering ram was successful, but the wood was quickly worn away, reducing the effectiveness.  So it was decided to construct one out of steel.

A search of miscellaneous materials lying around the shop yielded appropriate pieces of steel, including a short section of stout I beam, that would make a good battering ram.  Joel C cut the pieces to length, cleaned them up with a grinder, and welded them together to make the tool.  The next step will be to try it out with the Tie Inserter, and see how well it works.

Track Crew work party - more tie replacement
This week, the Track Crew was back at it replacing ties in the operating track.  The work was much the same as always – pulling spikes by hand, extracting the old ties and then inserting the new ones using the Tie Inserter, installing the tie plates, tamping using the Tamper, and then spiking using the Spiker.

Today’s work involved a number of switch ties at the South Park switch, and these are always more complicated.  To begin with, a switch tie always has about twice as many spikes as a normal tie, so it is more complicated right from the start.  Then it frequently works out that the tie plates are messed up for some reason, and this turnout was no exception.  It seems that in several places where there should have been

large tie plates with multiple spike holes (locations where the two rails are close together and there isn’t room for two normal tie plates), the turnout had been constructed with normal tie plates cut with a torch.  This isn’t as strong as using the right plates, so more appropriate plates were selected from our collection and used.  All of these things take extra time, so the overall productivity was lower.  However, it was a pleasant day with sunny skies and a cooling breeze, so no one was complaining.  The work crew this day was Jerry A., Joel C., Robert M., Bob P., Robert P., and Pete W.

One persistent problem relates to using the Tie Inserter to extract old ties.  The machine does this by gripping the tie by its end, and pulling it out.  However, with the deteriorated old ties which are being changed, it frequently occurs that the end of the tie will disintegrate and then the machine can’t do its work.  One solution that seems to work is to use a new tie or just a section of a tie as a battering ram, gripped in the jaws of the Tie Inserter, to push on the end of the tie to get it started.  Then the machine is turned around and works by gripping the tie at the other end.  While this is effective, it is relatively hard on the battering ram.  It seems like it is time to make a suitable battering ram out of steel, which will be more hardy.

Repairs to the Tie Inserter
With the next Track Crew work party coming up, it was necessary to get the Tie Inserter back together.   Earlier, the hydraulic tank was cleaned and flushed.  Now it was time to get the hydraulic system connected back together, filled, and tested.

Repairing hoses

A number of hydraulic hoses had been identified that were on their last legs, so this seemed like it would be a good time to get those changed.  Also, there was a part of the system where the previous owner had made some repairs using pipe fittings rated at 150 psi.  This didn’t seem to be a very good choice for a system that operates at 2,000 psi, so the appropriate hoses and high-pressure fittings were ordered.

The task sounds simple – unscrew the defective or incorrect hoses and fittings, and screw on the new ones.  As with everything about railroad maintenance machines, nothing is ever that easy.  The fittings and hose couplings are frequently difficult to reach with a wrench, and as soon as the hydraulic fluid begins to drip out of the open joint, the new fitting becomes very difficult to grip tightly enough with the fingers to get it started back together.  In the end, Joel C. was able to get everything together using a certain amount of persistence and plenty of carefully selected “words of encouragement.”

Finally, with everything hooked up, the tank was filled with new hydraulic fluid and the engine was started to test the system.  True to form, several leaky fittings were discovered.  Some of them were corrected by tightening them, but one needed to be replaced with a new fitting to get a good seal.  Finally, the machine was ready to replace ties again

Repairs to Tie Inserter
The next chapter in the never-ending tale of repairs to the Track Crew’s collection of old equipment is an overhaul of the hydraulic system of the Tie Inserter.  This machine was purchased by the Association last fall, but it is almost 30 years old.  A long life of hard work has taken its toll on the internal workings of the machine.  Some time ago, while repairing some leaky hydraulic cylinders, it became apparent that the machine swallowed something hard at some point during its life.  This caused significant damage to some cylinders, which needed to be replaced.  But before replacing the cylinders, a major expense, it seemed prudent to drain and flush the hydraulic system.  There was the possibility that whatever caused the initial damage was still circulating in the system, so the best course would be to flush it out before damage could occur to the new cylinders.

A few months ago, a replacement cylinder for the turntable center jack was ordered.  The money to replace all of the damaged cylinders was not immediately available, so at this time only the most important one was purchased.  The remainder of the replacement cylinders will be ordered later when the money is available.  With the new cylinder on hand, it was time to begin the process of draining and flushing the hydraulic system.

Joel C. brought the machine into the shop, and placed it over the pit.  An empty drum was selected and placed under the machine, and the oil was drained into it by removing the plug from the bottom of the hydraulic tank.  Meanwhile, other parts were removed for replacement or service.  The old turntable center jack was removed by lowering it into the pit.  The hydraulic return-oil filter was removed for replacement, and many hoses disconnected or removed to gain access to the tank for cleaning.  The head of the hydraulic tank was removed to flush out the interior.

One pleasant surprise was to see how clean the hydraulic tank and filters were.  To be sure, there were some metal flakes and bits of dirt, but nothing too serious.  There was evidence that the previous owners must have drained and flushed the system before, so perhaps they had made some attempt to address this situation.  With the oil drained, the tank was flushed with solvent and wiped clean.  The suction strainers in the tank were removed and washed clean, as well as the magnet inside the tank.  Finally, the liquid level sight gauge, which was almost unreadable due to age and deterioration, was replaced with a new one.

Just when it seemed that everything was going well, a problem came up with the new turntable center jack cylinder.  While the new cylinder was ordered from the machine manufacturer using the exact part number of the old one, and by external appearance looked to be an exact replacement, the new cylinder turned out to have much shorter stroke than the old one.  A quick call to the manufacturer revealed that the cylinder is a universal one that is used on several different machines, and has inside it a “stop tube” which limits the travel.  Apparently for use on this machine, the stop tube must be removed.  So it was necessary to dismantle the cylinder, remove the stop tube, and reassemble.  Finally, the new center jack was mounted on the machine using the shop crane.

The end of the day intervened, so the remainder of the work will need to be completed another time.  Still to go – replacement of some hydraulic hoses, reconnecting everything removed for service, and filling and testing the system.

Track Crew work party day
Once again, the Track Crew spent their work party day replacing ties. The work of this week was around the Car House One yard, and down the Branchline towards the Del Paso Substation.

The first order of business for the day was to replace some switch ties in the yard lead.  Over the past month, the Track Crew has strengthened these turnouts significantly by replacing many switch ties.  This day’s work finished up that work by replacing the remaining marked ties in the Branchline switch.  The Crew worked quickly to finish this work, in order to allow the Operations Department to get back to the business of running trains.  In fact, the Crew was ready to let the operations return to normal by the time they broke for lunch. 

Hand work required

The remainder of the day was spent replacing ties on the Branchline.  While this track is not in regular service, it does see some operation and therefore needed some attention.  By the end of the day, the Crew had changed all of the marked ties to the end of the Branchline near the Del Paso substation.  The Track Crew for this day was Jerry A., Mike C., Joel C., Mal E., Robert M., Bob P., Robert P., and Pete W.

With the completion of the work of this day, the Track Crew is more than half way towards the annual goal of replacing 400 ties.  Also, the ties replaced so far are without a doubt the most challenging ones of this program – the most difficult to access, the poorest condition, and the greatest number of switch ties.  This means that the tie replacement work is well over half complete for the year.  The remaining work will extend down the open track to the west of the museum, and so should be easier to complete.

Repairs to Tamper
The Tamper was due for an oil change, so it was off to the shop for that work.  The pit track in the shop is a convenient place to get under the machine for draining the oil.  So, Joel C. positioned the machine over the pit and the work began.
The Tamper has a big diesel engine, and it holds a lot of oil – almost 5 gallons.  While the oil was draining out of the engine, the oil filter, both fuel filters, and the air filter were all replaced.  The photo shows the engine compartment of the Tamper open during servicing.  With the new filters in place, the engine was filled with fresh oil and run to check the fluid levels. 

Also serviced at the same time were the batteries, which were filled with distilled water.  The machine was greased at its working points, and everything checked to make sure it would continue to work well.
