Little correction:
The last official number of "18 201" was "088 182-1". This number was valid from 1992 on. But it was never intended to be writen onto the locomotive. "×88"-series numbers were always intended for internal use only.

Those red filter slides are typically West German equipment. They were not used in GDR. And it's very improbable, that accomodations for them have been installed onto East German railroad vehicles after the fall of the Berlin Wall.
East German locomotives without separate red marker lights have always used the same EOT devices, also used with freight cars.


And here some images of the prototype:
I took these photos in Guben when "18 201" went to Poland for the very first time on April 28, 2007.

I'm planning to add a sound decoder to a Roco BR18-201. The attached photos show the locomotive disassembled.

This locomotive did not run well on the TT Tracks layout. On the sharp curves the middle driver shifted so much to the side that the electrical pickup dropped to the inside and kept the driver in an extreme position. The locomotive derailed all the time.

The photos show that the center wipers have been deformed from these incidents, and likely will continue to be a problem. I had a similar difficulty with a Brawa E95. The wiper blade can be bent back to normal, but if it isn't perfectly horizontal to the wheel, the spring pressure will force it to deflect again.

My cure for the E95 was to solder a bit of wire across the wiper, effectively increasing the width so it wouldn't drop out of place. I haven't done anything to this one yet.

Bill Dixon has written about making the curves larger on the TT Tracks layout. (tt-trak-t979-1010.html) His work on the layout curves also will help prevent these problems with longer equipment.

Just a though but, it might work better if you replace these wipers with new ones that work on the back / inside surface of the wheel flanges.
I have never been a fan of wipers that run on top of the flange. Eventually a grove is worm into the wiper and this can prevent the wheels from moving sideways on curves.

Your suggestion is a good one but I don't have the skill or resources to replace the wiper blades. I thought about just folding the wipers down to bear against the back of the wheels but their arrangement on the circuit board prevented that approach. I was very reluctant to undertake such involved work on this otherwise fine model.

Still, the locomotive wouldn't run properly as is. I soldered a bit of phosphor bronze wire to each wiper blade. I used .020 wire as shown in the first photo, but it turned out that there was not enough clearance above the wheels for this. I replaced the .020 with .010 wire which leaves barely enough clearance. After soldering I cut each wire to suitable length to prevent the wiper from dropping off the wheel when the wheel shifts sideways. It's not a pretty solution but it works.

If I'm still alive when the wiper gets worn down, I can solder on new bits of wire.
