Critique my Layout

Doug Kinsman ·
So I am brand new to SCARM and this will be my first "serious" build (currently have $400 of track on a 4X8). I want a mountain to run my shay on and at least two independent loops so the kids can control their trains without fear of a wreck. The reverse loops, although making the layout seem busy, I am hoping will provide a nice Mt. plateau for a logging scene on the elevation and the 2nd reverse loop will be mostly hidden by the plateau. Disregard the baseboard overhang and how close some...

Manual reverse switch assembly correct?

CountOrlock ·
First, let me apologize for blasting this forum with so many questions--I just like to reassemble my trains as accurately as possible, and there is no ultra-detailed manual on how to do this (wow, what an awesome book project!). Anyway, here is one question: when I attach the manual reverse switch to the motor housing, and then the rod jutting out of the top of the train, the rod seems to knock against the shell, almost lifting it up, and I can't imagine that this is accurate and I am doing...

PS3 steam upgrade reverse issue.

I had loaded the PS3 upgrade files and chain files for my challenger. Everything was working properly. In forward headlamp was on tail lamp was off and the reverse was true in going backwards. I realized I had loaded the file for an oil burner. I set about reloading with the coal files. Noticed hat the engine was running reversed for forwards and visa versa. I then reloaded the Oil burner files and the same situation exists. The Tail light is always on. Which wasn't the case after first file...

Need help with Auto Reverse Module for Trolley

Cathy C ·
I recently acquired a Pocono Mountain Lines Auto reverse unit or a push-pull some call it and I'm having a terrible time getting it to work for me. I've googled every which way I can imagine and watched every YouTube video I can find. The closest I came to assistance was on this forum in a post a few years ago. The module is wired to the power supply and the track is wired to the module. The instructions indicate dead, reverse and trigger zones, with wiring from the track to the module in...

Getting AF Alcos running again after layoff

milwaukeeroadtrackman ·
Hi - Once-running "original" engines that ran no longer do - it's the reverse unit. PLEASE DON'T WRITE IN TELLING ME TO REPLACE THE REVERSE UNITS. There's got to be some trick to get these things cycling again, they stop working after they sit too long. Right now they just light up but the reverse unit doesn't kick in. Can anyone tell me from experience what to try and in what order? I read about fingers, etc but don't see them or how to remove/clean them (if that's a thing). I see the drum...

They are tricky but you do get better the more you do. I wish there was a big secret but you do need 3 hands at least. I try to work from the top down when reassembling and hold the 'ears' as I get the individual pieces in place. First, the 4 finger, then the drum then the two fingers. It still takes me awhile though and usually quite a few attempts.

I just did one last week. The nub went bad on the end of the drum and the fingers shorted out. How do the guys who repair clocks hold everything in alignment while they reassemble the works?

Re: So how DID Lionel assemble those E units?

I believe Lionel had a special vise to help hold the unit. The number for this vice was ST378. Lionel also had a special tool to help spread the unit. Once the e-unit was popped open the fingers and drum fell out.

Not sure if it's still available, but a few years (at the suggestion of someone here on the forum) I found a video on YouTube on repairing/rehabbing E-units. It was in two parts and was excellent in terms of the video quality and the instructional end. Highly recommended if you can still find it.

I have the ST-378 e-unit vise. I find that it is easier to just hold the e-unit in my hand, so I don't use it. The vise that Bob Taylor shows is the modern equivalent. It is made by Hobby Horse. They were offered for separate sale by Hobby Horse. It was included in the Lionel Service Station tool package from the early 1990's. They are still available. Hennings also has a more elaborate vise / jig for assembling e-units. I have one, never tried it. I do use the e-unit spreader bar. I think...

Thank you everyone for your replies. This was a once in life time repair deal for a friend whose dad had given him the train. Engine was dead shorted and I found that the lamp lead had gotten pinched and rubbed through,and the E unit barrel was broken. The wire was easy, the E unit was a challenge. But I did it abeit, adding few more white hairs.

Another tip: The thickness of the e-unit spreader bar is the same as the spacing should be between the e-unit contact fingers. Here are the Lionel Service manual pages on postwar E-units . These pages make no mention of the tools because the pages predate the tools. I thought there was documentation on how to use the e-unit spreader, but I don't see them on the Olsen's site.

Re: 4 x 14 track plan

Once you go through the Red/Green switches and inside joining curve on the left side traveling left to right, you can't go through again without backing up. You might be able to join the outer loop as shown below.

Thanks for the suggestion. I'm still toying with the design. I'm not keen on switches at the backside (top) of the layout since it's along a wall. I may move the reversing loop to a different location to keep all switches in easy reach (at bottom).

Just so you know that your single reversing loop only allows changing directions once without backing through.

Re: Getting AF Alcos running again after layoff

milwaukeeroadtrackman ·
Okay ... good info ... so the latch goes through a slot and is limited as to how far you can "swing it from side to side" - as you suggested I moved it as far as it will go to one side, now (and yes, I'm an idiot) the engine runs in one direction, at least, but won't go into neutral and do the reverse cycle, is there some adjustment so that the lever moves between - are we looking for 3 states? both directions / neutral no direction at all / one direction operation? Thanks

It sounds like the brass pawl is not dropping without power and is stuck up. Something I learnt many years ago is that the top edge of the brass pawl will pick up dirt etc and this causes it to stick to the top of the black reverse units frame. Just leave the locking lever in the off position which you have done and and push the brass pawl down so it drops. Then get a Q tip and clean the top of the pawl to remove the grunge, you might find it comes off a green colour. Then use the other end...

I'm embarrassed - I'm 2 kinds of engineer and don't know what a pawl is - can you describe it and repeat what your saying, tailoring it not only for "dummies" but "idiots" LOL - seems like you've hit the nail on the head - what do you use for cleaning solution? Is acetone a no no? Rubbing alcohol? ???? Thanks so much! Tom

Picture two shows the end of the brass pawl in the opening of the reverse unit in the top right position. It sounds like it is stuck in this position with the locking lever in the off position and power cut. Just pushing it down with you finger will see it drop to the bottom of the opening. The bottom of the pawl will be resting on the bottom of the black frame. The top of the pawl will be exposed. I don't use anything on the Q tip to clean the top but there is no reason why you can't use...

As it hasn't been used for a while I would also look at removing both side frame assembly's to get access to the axles and gears. Depending on when they were last lubricated I would drop some oil on the axles either side of the gear so that it goes into the chassis. It may also need the old grease removing from the gears and new grease applied. The other place it will need oiling is on the armature bearings. These are more tricky to get to when it is all assembled together. I use a modified...

First off, I am not running 3-rails. I have HO and joined this O group because this was the only place I found that people seemed to understand the module on the posts I saw. My trolley works fine on the regular layout track, forward and reverse. I have the four places the instructions say to isolate joined with plastic insulated joiners. I've only isolated these places on the inside rail, not the common rail and I've done all the work at joints, have not cut any rail. So from left to right...

Re: Getting AF Alcos running again after layoff

I believe CRC-56 will leave a thin film of lubricant on all parts and some of this will be left on the pawl which will attract more dirt and cause it to hang up again. It may be good in some way but introduces problems again in the future.

Be curious what thos two large rectifier blocks are used for in circuit. Appears that Marty is right that its AC, though without seeing baord and tracing circuit, it might be possible to run on DC (note I said MIGHT be possible as it looks like the 13-20 VAC is rectified and stepped down to 5, 8 or 12VDC to run the timer, optoisolator and relay and most likely not interconnected at all with the AC train wiring) My guess is when trolley touches Trigger the optoisolator turns on triggering the...

Re: Need help with Auto Reverse Module for Trolley

Consolidated Leo ·
I'm not sure that the module that you've got there is intended for HO operation. I think it mentions AC and requires E-unit reversing solenoids. HO runs on DC and reversing is accomplished by changing the polarity of the power on the track. There are no E-units. This could explain why you've had such a hard time finding anything about it other than on the O gauge forums.

I believe I can see some other problems with your reverse unit which are going to cause a failure later on. In picture four if you look to the left of the red wires you will see a metal tab that protrudes through the brown finger board to keep it in position. It looks like someone has removed or replaced it in the past and not secured it correctly to stop it lifting which will cause the fingers to not make contact with the drum. They need to be twisted by about 20-30 degrees to lock the...

Well, I see that you didn't recognize that the difference. There are two other sources, Dallee Electronics -Automatic back and forth and Azatrax - continuous back and forth - that have systems that will work with DC. it's actually easier working with 2-rail DC for detection and control. I don't know if you discovered that there is HONGZ forum here , which for is for HO, N, G and Z scales. Many hobgyists run multiple scales. You can get some suggestions there.
