AFAIK, all W124 diesels came with block heaters, including especially your OM606. You may need to get a cord. The block heater is on the right (passenger) side of the block, just in front of the starter motor. You can either run the heater all night (it uses about 400 Watts) or use a timer – about 4 hours is enough to get the block up to about 40C. In addition to making the engine easier to start, you also get heat in the passenger compartment almost immediately.

You and my late father are the only people I have ever known to use the term "Pennsyltucky." Most folks look at me like I'm crazy or drunk when I spring it on them.
