I want to know the answer to the following question:
What type of locomotives are sometimes used on the Eritrean Railway to cater to groups of enthusiasts?
All the background I'm provided with is that "The most significant of these projects was the construction of a coastal highway of more than 500 km connecting Massawa with Asseb, as well as the rehabilitation of the Eritrean Railway.". Is that enough to answer the question?
Answer: no
