Lionel Chessie T-1 6-18011 Mods

Here's an update as to where I am currently with upgrading my Chessie Steam Special.

I have the ERR AC Commander installed in the forward part of the tender. I am using the MTH tether and 10 pin connector GRJ suggested. But I opted to modify the board to get it to fit in the original place on the tender. I opted to put the RailSounds board on top of the R4LC board. You can see in the second picture that I tried to put it on top of the speaker, but I couldn't get the body on. I plan on adding clips to the coal load so I can make the load removable.

I wanted to have a coil coupler on the tender so I got a Mohawk Hudson truck and modified the frame to fit. I think I'll hook this coupler to the "Front" couple on the Commander board, because I want to use the rear one for the Aux tender.

I removed the 6v constant voltage regulator that was used for the front headlight and firebox light. In its place I added the Super-chuffer to the engine and wired everything in. You can see the grain-o-wheat bulb for the cab light. I also added a small circuit I got off eBay for a flickering firebox. I have the LED hanging behind the motor in between the brushes.

More to follow tomorrow.

Chris - the mods are looking great (and very similar to my updates).

Thanks Allan. I'll have more this evening and my future plans with the Aux tender.

Here's the continuation of yesterday's post.

Here's an inside view of the tender with the body on. As I said yesterday, my plan is to add clips to the coal load in case I have to get to the volume control.

I started on the Aux Tender yesterday as well. The first thing I did was remove the IR sensor and drawbar from the front truck assembly. To make up the space I added a washer in place of the drawbar. I had a manual coupler that was sent to me by accident from Lionel. This is exactly the correct length I needed to attach to the front truck and the distance looks to be correct. 

You can't see it but where the coal conveyor would be I cut out the opening for the 4 pin plug and PCB I removed from the Chessie tender. My plan is to somehow use the original 4 wire tether and connect the two tenders. I'll probably end up drilling a hole as low and centered as I can on the OE tender body. This is only going to be for operating the rear coil coupler and the rear backup light.

Now, I have a few questions for anyone who wishes to answer...

1. The Mohawk tender originally has/had the railsounds in it. Since I removed the IR sensor and drawbar, Is there a way of operating this system via the horn and whistle buttons on my CW-80 transformer (conventionally) since I can't use my TMCC remote to activate them? Also, Does the IR board have to be installed for it to operate?

2. In the photo below, there are 2 lights on the rear of the Aux tender. Is the upper one a constant "on" and the lower one a MARS light?

Thanks in advance. This is all the updates to this point.

Allan, Did you leave the marker light on the rear of the tender or did you remove them? The photo of the aux tender doesn't have them.

Chris,

I removed the marker lights from mine since the prototype didn't have them.

Chris,

In regards to the Mohawk tender's RailSounds, is it the 1.0 version from the 1990 or the 3.0 version from 1998?

John will probably correct me if I'm wrong, but the 3.0 version probably just needs hot, ground, and serial data wire connections to a TMCC receiver. You could use the ERR dummy locomotive controller board to function that RailSounds board.

If you need to find more information on the Lionel T-1 look up the Lionel number 18006 as the Chessie engine is an exact copy of the Reading Lines T-1, just has a different Lionel part number and paint job to the best of my knowledge. In real life the Chessie System either bought or rented the Reading Lines T-1 2101 and re-painted it for the Chessie System and gave it a tune-up or minor overhaul as well.

Lee Fritz

Ross Rowland owned the 2101 having purchased her from a scrap dealer in 1975.  He restored her for use on the American Freedom Train.   When the Chessie Steam Special and the later Safety Express were brought about Chessie and Rowland entered into an agreement to run these using 2101.  Hence 2101 was used until the roundhouse fire in 1979 damaged her beyond repair.  Ross cosmetically restored her to her AFT colors and a traded her for C&O 614.  614 powered the Safety Express until they realized that the 614 was garnering more attention than the Safety Express.

It's the 1998 version 6-18064 not the 6-18009. From what I read from the instruction manual for the engine and tender the whistle and bell will still activate as in conventional mode using the buttons on the transformer. Just no tower or crew talk. So, unless I remove the baffle for the speaker I have no room in the tender for anymore trons.

Great work. I am not as patient when it comes to all these electronics. I will be having the same performed on my Chessie and Reading T-1 soon. I am going to have Henning's perform my upgrade.

Latest update on my Steam Special. I believe I have finished all the necessary wiring. I have the coil coupler and rear light on the AUX Tender connected to the 4 pin connector. I then took a leap of faith and drilled a hole in the back of the Chessie tender. Its barely larger than the diameter of the tether wire. Then I connected the tether to the AC Commander for the rear coupler and rear light. Although this wasn't the ideal situation for the tether wire, this was the only way to make this work. If I came from under the frame the rear coupler would have hit the wire preventing it from negotiating the curves.

I am now up to the point of programing the Cab 1 to the engine and seeing if everything works as advertised. Our first car show of the season is this coming Saturday. I have lots of Honey-Dues that have to get done in the next few days, But I'm going to try and get this thing programmed this week. With everything modified this is now an engine and dual tender combo. Painting of the Aux tender will happen sometime this summer. I have the paint, I just need to get a good quality airbrush.

Much thanks to GunRunnerJohn for his electronic and wiring advice. Also, much thanks goes to C&O Allie for his help with answering questions about his Aux Tender. More to come hopefully later this week.

Thank you to the rest of you that provide kind comments. Its greatly much appreciated.

I was able to run the engine yesterday for the first time. It is a learning process for someone like me that has never used TMCC. Once I got the Cab 1 figured out, I was able to test all the functions. The only Oops was the headlight and reverse lights were backwards. I double check my wiring with the directions for the AC Commander and it was correct. The directions has the 2 lights backwards. But swapped the wires for the lights and everything works as advertised. Super-chuffer is awesome! With the body on the engine, it looks like the prototype when puffing. I'll try and get a video up by the end of the week.

I found out the RailSounds in the Aux tender will not work by itself conventionally. But, this is no big deal. Don't need it. Might just sell everything internal. Its much heavier than the Chessie tender.

Odd that the headlights are backwards, but I'd check the documentation again.  I just wired up two of the AC Commanders, and the lighting matches the documentation for me.

This is the instructions I used. I put a binder together with all of the necessary paperwork. Maybe I just read it backwards.

That's the same version of the document I use for the AC Commander.  All of the similar ERR TMCC boards use the same mapping for the lights and smoke on the 7-pin terminal block.  Note that the AC and DC commander differ only in the first two pins next to the antenna.  For some odd reason, they removed the chuff input and duplicated the antenna connection on the terminal block.  Of course, that moved the PGM/RUN switch connection, an unneeded duplication and omission.  However, in all cases for all of these products, from pin 3 common through pin 7 feature, the mapping is the same.  Since this is hard-wired on the motherboard from the R2LC, it's pretty inconceivable to me that the two light outputs could be reversed.  I've installed dozens of these boards, multiple copies of any specific type.  That's always been true for all of them for years.

You do very nice work.

Thank you very much!

Here's the link to the video I did this afternoon. The power supply for the railsounds in the aux tender melts down at the end.

Chris,

Sounds great!!  Here is your video embedded so users don't have to go to Youtube directly.
