♫Train, Train. Take me on outta this town.♫



Recently, MarineDiesel has had a number of inquiries regarding the provision of engines on locomotives. We are specialists in engine customizations. We take engine blocks made by our partners and modify them for different customers’ applications.

Passenger trains present a number of different technical problems for railways.

  1. They must be extremely fuel efficient.
  2. Space for the engine to be mounted is typically exposed to the elements and very tight.
  3. Fuel lines can be long and exposed to damage.
  4. Climate can wreak havoc on cooling systems.
  5. They require a very different torque curve than boats. Very high torque on startup with decreasing need at higher RPM.
  6. Relatively few engines for small locomotives are manufactured, especially for light passenger rail. Most locomotive engines are designed for long, large, freight trains.
  7. Alternative fuel is often desired due to extremely strict emissions regulations, rendering old engine designs unacceptable for current requirements in many locations.
  8. Locomotive engines require extremely long life cycles and will be rebuilt eight or more times over the average service life of one million kilometers.

MarineDiesel’s industrial division, MDPT,  has the knowledge, experience, and capability to successfully engineer, commission, and test these specialized engines. Fuel efficiency and service life have vastly improved over the last 30 years, the average age of engines in many locomotives. In fact, greater fuel efficiency alone can usually justify re-powering locomotives, with quick payback times generating good financial incentives to justify the purchase price.

We often work with Mercedes Benz on these projects, and have completed numerous projects with different railways in Europe and Asia.

Maintenance Tip of the Week – Gaskets 06/30/2014



Maintenance Tip of the Week


Always change or replace gaskets as a set. If there is wear or leakage on one, all are probably worn.

Interview with Andreas Blomdahl, MarineDiesel CEO



This week’s article is an interview with our CEO, Mr. Andreas Blomdahl. Andreas will be contributing periodic columns to this site in the future, keeping MarineDiesel customers up to date with the latest developments coming from the very top.


Q1: Why did you start MarineDiesel?

Coming from and engineering background and doing some racing for a while it was clear that the products on the market where very old in design and that it was time for someone to think outside the box in the marine industry. The goal from the start was to bring something different to the market, a more powerful while durable product in a small package, I feel we have succeeded in the VGT engine line.


Q2: What was your biggest challenge in setting up MarineDiesel?

The marine industry is a very small industry especially on the engine side, mostly the same companies that have been around for a long time. The main challenge isn’t so much the products as to establishing distribution worldwide, this takes time and on the technical side the emission will become a challenge for the future, rightfully so as the marine engines are far from what they are capable in regards to emissions.


Q3: What are MarineDiesel’s goals for the future?

MarineDiesel will continue to manufacture the world’s best performance marine diesel engines for the commercial and governmental markets. Any new products must meet our strict policies as we are in the backbone an engineering company that also has a production of marine engines.


Q4: Where do you see MarineDiesel in the next five years?

MarineDiesel is currently expanding its distribution network and increasing production capacity in order to meet current and future demand. MarineDiesel will be recognized for putting out some cutting edge products on the market over the five years to come.


Q5: Any new developments coming in the next year?

Yes, there are but unfortunately I can’t tell you about them so just keep your eyes open.


Q6: What are the biggest advantages of MarineDiesel’s products over the products of its’ rivals?

We have market leading power to weight ratio on our products while designing them from day one for the commercial field, not for pleasure crafts. Apart from the products, our organization is set up in a different way where we ask our customers how we best can assist them in regards to training, support etc, most of our competitors tell the clients how it needs to be structured instead of listening to individual requirements.


Q7: What has been MarineDiesel’s biggest success?

The VGT engine series


Q8: Anything you wish you could have done differently?

Many things but we try not to dwell on the past but to improve and look to the future, it’s more productive.


Q9: Any further thoughts?

Make sure you get a test ride on a vessel equipped with with VGT engines. It’s a completely different animal to what else is on the market today. 


Founder and CEO.

 Andreas Blomdahl, 43, has been the CEO since 1992 is also on the board of directors for Marinediesel as well as a few other Scandinavian companies.

 A native of Angelholm Sweden, Andreas has an engineering degree from the university of Lund and has a long time passion for the marine field.

Ask Professor Diesel – 06/23/2014


This week’s question comes from Rajesh in India:

Professor Diesel, when I start up my VGT engines, there is a chirping noise. Is this an indicator of a serious problem.


A brief period of chirping is normal upon startup, usually due to buidup of condensation or moisture on the belts. This sound should disappear after a few seconds. If it persists, in normally indicates belt wear and you need to examine and replace the belts if they are worn.



Ask Professor Diesel – 06/16/2014


This week’s question comes from Mike in Australia:

Professor Diesel:

My VGT engine is electronic, so that means I should be able to perform diagnostics on the engine myself, correct? Can I buy something to receive this information, or must I go through a dealer for service.



Mike, the engine’s ECU is accessed through a special connector that we can provide and read by using software on your laptop or tablet. The ECU unit itself is set to customer specifications at the factory and is maintenance free.

Please note that we are often hesitant to sell this item to individual customers for several good reasons:

It requires training to understand the output and fault codes.

The ECU that we use is programmable. Entering information into the ECU can seriously damage the engine or hamper performance if done improperly. This software is not Angry Birds… it is not intuitive to learn, and if you make a mistake, it is often expensive to fix (no simple log in and get another “life”).

Dealers use this software as a diagnostic tool only, on site, so they can quickly diagnose and repair engine problems. It is usually best to leave the ECU to them.

If you have a question you would like to have answered, simply submit it in the form below:

Maintenance Tip of the Week – Vibration 06/16/2014


Maintenance Tip of the Week



If vibration noticeably increases and persists, one of the first things to check should be the condition of the engine mounts. Worn mounts should be replaced.

Life Cycle Cost Calculator



At MarineDiesel, we often come across potential customer who are confused about which engine to purchase. Yes, there are brand loyalties at play in any power decision, yet, more often than not, cost and price usually plays the biggest part in purchasing decisions, often eclipsing performance or technical requirements.

However, when choosing between two engines, much more goes into the cost calculation than simply purchase price.

Yes, very inexpensive engines are available in the market, usually, but not always, produced in China. Though these engines may be cheaper to purchase outright, their real cost becomes evident when maintenance, service life, and fuel consumption are taken into account.

When choosing an engine, you need to look at the following factors:

Purchase price

Engine rating

Life Cycle

Time between overhauls

Time between service

Fuel consumption

Cost of engine downtime

Cost of spares

Cost of service / labor

All of these factors add to the real cost of an engine, and in comparing one engine to another.

Therefore, in order to make your purchasing decision easier (Whether you choose us, or not), we have made the calculator below available for download for your use, free of charge.

Simply fill in the blanks indicated by yellow, and your real cost is indicated at the bottom. The spreadsheet is pre-loaded with the data from our VGT Series.

We hope you find it useful and helpful in making engine comparisons.
