IHB Michigan Avenue Yard and Tank Car Explosion

(see below for satellite information)

I learned about this yard while trying to determine where a propane tank blew up in a tank car cleaning facility.

Gabe Argenta commented on a posting
According to comments, it was the old UTLX 86 cleaning company and is now the Lakeshore Railcar and Tanker Services. Google marks it as United Rail Services.

Alan Craig commented on a posting
The above photo allowed me to determine the exact location of the explosion. Basically, the white building on the right no longer exists.

But the key comment in terms of learning railroad yards was: "Herman Lund It's off the south end of the IHB Michigan Ave yard." It is a large yard that is still a yard, as opposed to an intermodal facility. According to a B&OCT map, the tracks to the northeast are also part of this yard.

I'm gonna have to get you a photo of the CSX candy job [Ferrara Candy Company] passing this exact spot so you can see how little has actually changed here. Very neat, Mark

The caption raised the question: where is Austin Yard?
The yard the CGW leased from the B&OCT was called the "Chicago Transfer Yard" and it lays just south of the Eisenhower Expressway between Cicero and Laramie Avenues in Chicago. The yard is lightly used today by the CSXT to serve a couple local industries. CGW freights normally operated directly into the B&OCT yard and the power layed over there, while the small amount of local traffic CGW handled was set out and switched at "the Transfer". [Trains]
It would have been the 48th Ave. Yd. on this map:
B&OCT Map
As usual, there were more, and longer, tracks in 1938. But I'm surprised how much vacant land was south of the yard. I'm used to seeing a lot of "brown land" in today's aerial views of railroad and industrial areas, but I'm not used to seeing what appears to be a lot of torn down industrial buildings in 1938.

Twin Bridges over the Wabash in Bluffton, IN

Even on the east side of Indiana, the Wabash River was wide enough that towns thought twice about building bridges across it. The multiple postcards made of the twin bridges is an indication of how important they were to the community. To this day, there is only one road bridge. I assume the railroad bridge is the Cloverleaf because it was originally narrow gauge. I'm guessing the Cloverleaf was later realigned to cross further downstream to share the Lake Erie & Western route through town. But the road bridge does not look like a predecessor to Main Street because of the sharp curve at the end. I would need to find Sanborn Maps to determine where these twin bridges crossed the Wabash. (Note to self: the album these photos are from contained several covered bridges.)

NS/NKP Bridge over St. Marys River in Fort Wayne, IN

(Bridge Hunter, 3D SatelliteStreet View from Main, Street View from Sherman)

The satellite and street views would be of today's NS/N&W/NKP bridge. This 1889 bridge would not be able to hold the "big steam locomotives" that NKP ran in the 20th Century.

[Since the NKP used the right-of-way of the Wabash and Erie Canal, there probably was an aqueduct here over the St. Marys River in the mid 1800s. (Update: Tom's History describes the mill and the covered aqueduct that proceeded this bridge.)]


Becky Osbun also posted
Rick Brandt The view is looking North. The trestle seems farther away, I think, because the original Main St bridge was farther South than today's bridge.
Randy Harter This is the Orff Mill, however, it had other names/owners over the years. The mill was on the east side of the St Mary’s, just south [actually, north] of the Main St bridge. The tiny triangular shaped park there on Main with the statue of the boys who swam in the aqueduct is sitting in the eponymous Orff Park. While this was originally an overshot mill driven by water diverted from the Wabash & Erie Canal (which closed in 1874) in this photo we can see the smokestack indicating it was has been converted to steam engine.

BSNF/Santa Fe Bridge over Spoon River near Dahinda, IL

(Bridge Hunter, no Historic Bridges, Satellite)

I would have ignored yet-another-railroad bridge until I noticed it was over the Spoon River. I remember Spoon River is where the KJRY had a truss bridge collapse. Fortunately, railroads are much more willing to maintain truss bridges than IDOT is. This is a pin-connected Parker truss that was built in 1910.

The track speed is high for such an old bridge.(new window)

Since it is the Chillocothe subdivision (former Santa Fe), I thought it would be just the usual collection of pigs, stacks, and racks. But there is a mixed freight train.

Indian Lake Spillway and Miami & Erie Canal Feeder

(Satellite, 52+ photos)

Jack Hines posted
4000 working at Indian Lake spillway, Russell's Point, Oh.
Keith Moore I ran there 40 ton grove there for four months Reese is the operator on the 4000 does a great job of it solid dude for sure
It appears the spillway designers tried to ensure that only a small stream of water would go over the spillway because a long dam feeds water under a rather short bridge. With only a small stream over the dam, I would not think it would be a drowning machine. I wonder why it is being replaced with a V-shaped dam design. It looks like it needs to be replaced because of spalling on the dam's surface. And it does appear that the flow can get rather heavy even with its long length. So if you are going to build a new dam anyhow, it might as well be of a modern design. They are also installing erosion mats on the downstream side.

Satellite
When I saw how big Indian Lake is, more than a couple of miles wide, I wondered if it was built for the Miami and Erie Canal. The following map confirms that Indian Lake was a summit lake for the canal. That is, it is a lake built near the summit of the canal to store water for the canal to supply water during dry seasons. There should have been a gate structure to let water out when the water level was below the spillway to feed the canal. They must have removed the gate structure since the canal feeder function is now obsolete.

A 1938 aerial view shows the tracks the viaduct was crossing.
The tracks were part of the Erie Street and Grand Avenue Yard.

As Historic Bridges points out, the swing bridge was replaced by a wider bascule bridge in 1915, but a wider viaduct to feed the bridge was not built until 50 years later. By the 1970s, the rail yards in the city that supported industries and passenger car service during the horse and buggy days were disappearing.

Bending Crawler Crane Booms and Servicing Power Towers

It seems to be standard operating procedure for telescopic booms to bend under load. But I'm now seeing photos of a truss boom on a crawler crane bending when it is first raised. I've already learned that windmill farms and windmill transport are good markets for crane services. The 460' barge mounted crane below and the Facebook posting I added at the end teach me that electric power transmission towers are also a good market for cranes.


A big deal in operating a crane is the radius of the load. As the boom is lowered to increase the radius of the load (the distance the load is from the pivot point), the more the center of gravity moves towards the load. If the center of gravity moves too far, it is no longer over the crawler tracks and the crane starts tipping. To keep the center of gravity centered over the tracks is why they add counterweights to the back of the housing. But if you add too many counterweights, then the crane will tip over backwards when the boom is in a raised position. When a boom is lowered to the ground, the weight of the boom itself can be too much load for the counterweight. Historically, the crane they used to help build the crawler crane would also help pick up the boom until it was high enough that the crane's counterweights could balance the boom.

In the past, crane designers solved the balancing of load and counterweights by extending the size of the pivot point using a second set of crawler tracks (stinger or X-tender), a ring, or a weight wagon on the back. Now they use VPC (Variable Position Counterweight). That is, the counterweight is mounted so that it can move towards or away from the pivot point as the load and/or radius changes. With VPC, the crane can push the counterweight out far enough to balance lifting a long boom off the ground. I've recently come across some postings that show the bend in the boom when it is raised off the ground. I think it is different people taking pictures of the same event.

Chuck Brower posted six photos. The comments indicate the boom is 460 feet and it can be raised without an assist. It also points out the "midpoint lines."
Jim Browne The extra pendants are well ahead of the mid-point to create counter-moment in the boom that resists the bending moment along its whole length. At high boom angles they apply very little moment as the boom is no longer bending as much. Its pretty clever.

Even I know a boom is not supposed to bend like that.]

[Some of the comments are critical. For example the worker walking under the load, the use of a spreader bar for a point load, and the crane is overkill for the job. There are also some comments about the "dead zone." But I don't know what/where the dead zone is so I don't understand those comments.]

I assume the challenge below was the long radius needed to reach the tower from the nearest access point.
